It's so nice to see MDs that like to teach. I'm a nurse and have had too many encounters working with MDs that just not seem passionate about their jobs. I feel I even used to hinder patient advisory because I was afraid of speaking my mind to MDs. Now, I go distances because I know in the end the ones that don't care won't remember me and they ones that do thank me. Keep up the good work. You have a true calling.
+theedexitvideo I just had my first experience with this drug the other day I was in the hospital for sepsis and other reasons, 6mg to start , they almost had to go a 2nd round with 12mgs, but the Dr decided to try a different medicine thouth.
@Kathrina I was referring to becoming a better advocate for my patients. In other words I speak up for my patients. Where as before when I was a new nurse I’d just go with whatever the doctor said and didn’t offer suggestions. I’m doctors and patients eyes and ears. So next time you’re a patient pay attention.
I tip my hat to the dude that invented / discovered ADENOSINE I've had it twice, feels like you die stops the heart and re starts it kinda like rebooting ya modem
In my first experience ( and i do hope i wouldn't need it again), i felt the medicine crawling in my veins really fast. And then kaboom! It feels like a firework that just blown all over my chest and i needed to catch my breath after. And the next thing is like me trying to comprehend what just happened. And everything went fine. They gave me 3 of shots of that. I felt it 3 times. At first it was weird feeling, 2nd it still weird. Last shot i think i got used to the feeling and i think i am liking it. 😂😂😂
It's extremely difficult to explain to someone who doesn't experience it XD But yeah, it's extremely trippy, I always tell the nurses that I enjoyed the feeling since it's similar to a rise in adrenaline so I always manage to suprise them
I was born with SVT. For some reason, about 18 years old it kept coming unstopped. Adenosine is a hell of a drug. I tanked so fast when the SVT's hit, that they never waited to get me to the hospital. The paramedics always hit me with the drug as soon as they got vitals. The feeling of going from 220 bpm to a normal heart rate in a few seconds is crazy. Always did the trick. Glad to live in the US where paramedics have that on hand!
From Australia had svt for 28 years undiagnosed highest rate 248bpm in my state Victoria ambulances don't carry adenosine but have gone interstate and ambos have administered it on the footpath, at my local hospital after the 10th or so episode they always knew I was tough to cardiovert so they eventually just gave me the 24ml of adenosine in one hit rather than 6ml failing that another 6ml then failing that 12ml and the 24ml straight up didn't always resolve it so defibrillation was the way to revert me to sinusoidal heartbeat and eventually had a catheter ablation
@@DiosaDe1So1the nurses described it like the initial drop in a rollercoaster, or that feeling of descending in an elevator. Everything just drops. I remember feeling like my heart was gonna flop out of my chest: adenosine was administered and everything just dropped, went limp for a moment. Was super disoriented and shaky for a few hours after. Doctor explained this was because I had basically just “ran a marathon” (242BPM) to just walking a flight of stairs (a steady 120 BPM, eventually lowered throughout the night)
I've had svt episodes my whole life and let me tell you, it's terrifying! Best relief ever when it finally stops. Never had any emergency treatment for it tho

Very slick in not showing the patient’s facial reactions and vocal expressions when it “ hit” her. Also understanding that you don’t want to alarm a patient but downplaying the effects of this drug “ nurse says it will make you feel WEIRD!” So glad I have seen enough of these videos to be knowledgeable enough to be able to submit or not submit to certain treatments and procedures
Im 17 and I have dealt with this my whole life, the majority of the time I had to go the ER, they always pushed Adenosine, I had a surgery, and the doctor wasn’t able to fix the problem completely the first time, because I had two extra electrical lines, well he was afraid if he kept going he’d hit my normal line and I’d end up having to have a pacemaker, well my problem just kept happening, we waited about 2 years and did another surgery and it was successful, I have not had SVT since.
I remember those days. My heart would shoot up instantly to between 200-300 bpm. My shirt would look like it was just vibrating on my chest. Most times the episode would stop on its own (I had episodes 4-8 times a year usually), but occasionally it wouldn't stop and I would need the Adenosine. Adenosine caused chest pressure and tightness for me but the first dose always worked. I finally had my RFA surgery in 2012 and I haven't had an episode since! I did wake up in the middle of surgery due to the adrenaline they use to cause the tachycardia. I felt somewhat paralyzed but I could see what was going on. I could see my heart shaking away on the monitors. They got me under again quickly, but it was kind of cool to get to see the doctors working on my heart while I was supposed to be asleep lol!
Wow 300bpm, that's virtually a death sentence for most people, medical information suggests people starts dying at 250 depending on their age health condition and body make up everyone is slightly different but haven't seen any concrete evidence of ecg of a heart rate near the 300 I have read it's possible haven't looked for info on over a decade so who knows what's been updated since then
Similar story here. First two episodes resolved themselves, third time was a trip to the ER and two hits of adenosine (don't remember how much, but it was two injections). Had my ablation in March just before the Covid restrictions started.
@@nihilvox As im not sure if Anne is still active on her account i'll just reply to you. I've had 2 SVT (AVNRT, to be specific) episodes that's ended up with an ER visit. Other than that i'd say about 5 ish that resolved themselves within a few minutes. Had an ablation in either late march or early april 2019. January 2021 i suddenly got another AVNRT episode (2nd ER visit) because as it turns out i had 2 reentry circuits and they missed one. The EKG from the ambulance showed 258BPM at the highest but it was hovering between 245-250 mostly. I did not have to get adenosine as it calmed down about 3 minutes before arriving to the ER and i was somewhat stable with sinus tachycardia at around 120BPM instead. Going to have a followup december this year and schedule another ablation, only problem is my 2nd reentry circuit is believed to be very close to my av-node so the risk of me ending up with a pacemaker is higher than the previous ablation so im nervous as hell.
I was taught in nursing school that carotid massages are not commonly practiced anymore. If there was an atherosclerotic plaque in the carotid artery and you massage it loose the patient is at risk for a CVA.
I was once in the hospital for fast heart rate they asked my mom if I had to be shocked or if I had to have denizen they put the pads on me just in case they had to shock me but they didn't .my mom told them that I had to have denzien
I would love to watch more videos like this. It greatly aids me in my preparation for the nursing Nclex exam. Being able to observe how things function in real-life situations is invaluable. It truly brings me joy to witness the Medical Team saving lives. Well done, everyone! ❤🥳👏
I'm really enjoying the more advanced videos mixed in with the more "fun" entertainment ones (namely abscesses), it's great to see cardioversions actively occur.
This has got to be the coolest thing I've seen. I've actually had SVT once, but my BP maxed out at 180 bpm. After an hour or two, the rate went down by itself. I was 18 at the time.
@@bopsandbangers It's scary to say the least. Yes, caffeine can do it. Sometimes it can happen with other medications. Just to be safe, make sure to follow-up with your doctor. As long as I avoid my trigger, I don't have a problem. ;)
The only warning was from who I assume was a nurse that it’s going to make you feel “ weird?” Fortunately I watched enough of these to know better but if somebody administered that to me without warning, you calling security instead of the crash cart.
Wow 205 bpm! I recently had pneumonia and went to the doctor for that and she told me I had a very high heart rate (156 bpm) and she was concerned something was very wrong, one thing led to another after that was flushed out with saline, I was put in an ambulance and transferred to another hospital after they gave me a med to try to lower that and it lowered to 37 bpm and bp 60/30, at the other hospital they did a cardioversion and that fixed it but I was in the ICU for 4 days. Turned out I have a mitral valve prolapse that should be repaired, sooner than later. I had no symptoms at all with the 156 bpm and it was probably going on 1-4 weeks with the pneumonia.
A-Fib is no joke. Family history, clotting distorder, etc. Odds are not in my favor. I had first hand experience with Adenosine this past fall after a stroke. I was in A-Fib on the CC Bus. BP was about 160/120s & P was in 180+. When that Adenosine gets in your system, you literally feel like a yo-yo. Like someone pulls your heart out of your body and slams it right back it. Like a roller reaching the peak and then going down the bottom. It hurts! REALLY. It truly hurts. Patients should be administered pain meds every time cardioversion is done and they're awake.
To be honest when a person who has this says it doesn't work believe them and help them as soon as possible. I say this because I know I will try everything in the book before I call for help and when I call for help it is already too late. Although doctors may not see the urgency in this it is very scary and frightening. Your heart is making hormones shoot off and it causes you to stress out like crazy. So those hints he is telling her should wait until she is stabilized. IMO I have SVT and I have an ICD. I also had ablations
i recently had a rate of 229 and after drug it went down to 62 then up to 110. that feeling when you 'reset' wow. nurse said to me its like impending doom like im going to die, they were true but wow i felt the blood rush back to the rest of my body and felt 80% better. now just waiting to see when i can have an oblation. fingers cross soon.
My count of the times I've had Adenosine I lost count at 35 I have Brugada Syndrome and I have had SVT because of this since I was diagnosed at age 4 I'm 21 now and tired of the arrhythmia, Ablation doesn't work and I have an ICD now
Hey think of it this way, if you where born 100 years earlier you would have like 0 chace lol. So your pretty lucky to be alive today. Idk maybe that came out negative im just tryna be positive 🙃
Quick story about my initial experience with Afib. Few years ago I went to Cuba with a couple friends - two of them work in Emerg; great doctors. Long story short, I overdid it with the binge drinking and senioritas. One last debauchery, is what I thought to myself. BIG mistake. I was well aware of the fact that this kind of Reckless Behavior could potentially trigger an arrhythmia, but I never thought it would happen to me. We flew back home, went our separate ways. That night I felt extremely dehydrated, and very anxious from the glutamate rebound, worst hangover of my life. Few hours later as I was eating pizza, I felt a flutter, then the tachycardia set in. At first I thought I was going to die, then I thought to myself, if this was extremely serious, I wouldn't be cognizant, of anything, I'd be dead. I composed myself ,went to the hospital. White T-shirt covered in pizza sauce, hyperventilating etc. Not a good look. The nurse gave me a quick EKG, I was in AFib. A few seconds later the emerg doctor walked in, looked at me and asked me: Adenosine or C-version? I chose adenosine. I wasn't ready for this Beast, never again. NEVER. The feeling of impending doom, is real. I tip my hat off to any individual who has been administered this drug on more than one occasion. By now you probably figured out that I work in the medical field. Here's some simple advice to anyone reading this for whichever reason: Treat your heart with respect, eliminating all behaviors that lead to heart disease is paramount. It's an incredible/fascinating organ. ❤
Hello, Cedric. Similar story here as I have afib and alcohol triggered my first in 2017 after a weekend of binge drinking with friends. It started on monday right before sleep after a normal day and I knew those parties were the cause when the ER doctor said it seemed to be a "holiday heart syndrome" case. Recently I had a second episode. Those familiar weird palpitations woke me up - no apparent reason by the way - and I went to the hospital extremely calm and already certain about the procedures I might be submitted. Rapid afib confirmed and this time they decided to give me adenosine. No questions asked. First a shot of 6 milligrams, then 6 more. When that drug hit me I just panicked. By far the worst feeling of my life. It was like a near death experience. The doctor had warned that patients usually describe it as a roller coaster ride, but it's way worse. So in your case I supposed it worked, right? It didn't for me after all that. It kept me thinking though that adenosine shoudn't be prescribed for patients with atrial fibrilation, but what do I know?
I'm thankful that I am able to self revert will valsalva... I almost had to go to the hospital but a nurse friend of mine had me out my face in Ice and breath, then did a jugular massage and it reverted. 👀
Howl yourg OMG!! 302!! I can’t Imagine how that felt! I would be passed out because at 180-199 bmp I felt like I was going to pass out. Thank god you’re ok 😊
I was working on the helicopter(I'm a flight paramedic) when that episode happened, I suddenly felt really Ill then my ICD shocked me so I asked my coworker to run a 12 lead and the defibrillator could barely register my rate it was so fast so they put an IV in and gave me Adenosine with NO Sedative because I usually had low blood pressure and let me tell you it feels absolutely horrible having Adenosine with out a sedative
Had problems with this in the past - 1960’s and 1970’s - treated effectively by an aramine drip. I recall the feeling of relief the instant the drip “kicked in” and halted the arrhythmia.
Just in case anyone wonders a little bit more what it feels like and maybe a funnier way of thinking about Adenosine, I had to take it last year right before Christmas because I got an svt episode lasting about 4 hours and I finally gave up and when to the emergency for the first time (Good thing, too, cuz that set me on the road for the wonderful catheter ablation that cured me
Yellow lines on the GE Patient monitors are basic rundown colours, that's why GE has been around for years. The colours you selected on GE Patient monitors are basic rundown yellow colors, Classic neon green and mainstream colours which is really AMAZING,
So...the doctor is requesting the patient to bear down in order to increase intrathoracic pressure also known as the Valsalva Maneuver. In response to the increase in pressure, the body's parasympathetic nervous system responds and increases in activity. The subsequent increase in parasympathetics slows down the heart rate, providing rate control in a patient with SVT. There a whole host of maneuvers that are non-invasive and are at the disposal of healthcare providers when a patient is in SVT. Most of the time, patients require more intensive intervention such as chemical cardioversion (w/ adenosine) or cardiac cardioversion with a defibrillator. The key is the "increase in parasympathetic activity, which slows down the heart rate." Theoretically, anything that accomplishes this could be attempted.
chargerpride123 Bearing down hardly ever does it for me. Dunking my face in ice water, sometimes. Usually what works is gagging myself with my fingers...and even that takes a few tries. I was told NEVER to massage my neck, as if done wrong can lead to asystole. If vagal maneuvers don't work on my own after 10 minutes, then I go to ER
+Julia Despain It wont lead to asystole, it could throw a clot and cause a stroke in an older patient. Asystole is noted as a flatline on ECG with no electrical activity in the heart. That's not going to happen by massaging the carotid artery in your neck. 12 mg adenosine worked for me.
I always needed 3 shots to correct the episode. I would wake in the night when an episode came on. I’d get dressed without waking my girl and drive myself to A&E. I’d get reverted and rest under obs for hours then head back home and rest before she woke. One time I drove myself there and didn’t make it inside in time. I collapsed in the car at 3am and was found by a guard. That was the end of self drive care.
Good drug. When your lay there in a hospital bed with a heart rate at 240 beats a minute. Nothing else has worked. This did work. 6 hours later I was asleep after it was decided I should stay in hospital and my heart kicked off again. Best thing to ever happen cause the doctors worked out in a moment what had twiggered 2 svt episodes so close together and I've not had a problem since
My daughter was born with Wolf Parkinson White syndrome. She actually was in a breakthrough at birth, delivered by emergency C-section. At that time, open heart surgery was the only method of finding the extra pathway. After 15 years of using adenosine, vehicle maneuvers, and electrocardioversion, she was able to have heart ablation using intervenous methods. I'm very interested in WPW - have you ever had a patient with WPW? And how did you treat it?
300? Do you have heart damage from that? Cause I thought at that rate it's already a heart attack because of the heart isn't filling with blood!! May I ask how old you are?
This is really late so you may have found your answer already. The heart has 4 chambers, atria are the top 2 chambers and ventricles are the bottom 2 chambers; both are given electric signals in order to squeeze blood. SVT is short for supra (above) ventricular (ventricles) tachycardia (fast heart rate), a condition where something above the ventricles of the heart (the atria) is beating very fast due to of rapid firing of electric signals. This causes the heart to pump faster than 160 beats per minute-the average is generally 60-100. The heart isn't designed to pump so fast for so long and it'll eventually tire itself out, causing the heart to possibly go into V-fib (ventricular fibrillation-where the ventricles start to seize instead of pumping blood) and/or shut down.
@@tiffanyh629 I had this to happen recently, and so when my heart rate wasn't going back down after hours of this, I went to the ER. On top of this, I have had a prolapsed mitral valve for years. Also, in between jobs currently, so no health insurance. However, I am very grateful to still be alive!
I had 3 SVT attacks today in a one hour period. Very painful and felt like I was gonna pass out. I was given adenosine in my 3rd trimester 7 months ago. My heart rate was 230. It is a very scary feeling having that drug pushed when you are pregnant. I have had problems since I was a teen and have been on inderal since I was 18.
Hi can anyone help me, I’m 18 year old girl skinny healthy weight- my bpm is always around 80-105 while sitting down or resting while I’m walking it’s 100-140 while running for a short period like 3 minutes it’s 160 I get chest pain arm pain and extremely out of breath any ideas on what it could be
First stop worrying too much because it's probably your worrying that's making it a little fast, you are very young and your heart is doing it's job of beating. Might be a little fast but nothing major. Let your GP send you to a good cardiologist for stress test, ultrasound and an overnight holter monitor attachment. He might decide to put you on beta-blockers that slow the heart if necessary. But if you're an anxious person then this is anxiety related.
Yea that drug is no joke!! 👍 Feels like a 1000ft. roller coaster drop in 3 secs flat. But still better than being cardioverted while conscious. Which feels like being hit by a train head on. Which do you prefer?
I dont know what I was given for tachycardia but it was a tiny pill half the size of a saccarine pill and 25 minutes later it SUDDENLY kicked in and my heart rate went from 156 bpm to 37 and bp to 60/30 and I was feeling bad, vision going and massive sweating, they had to flush it out with IV's and 20 minutes later I felt better.
@@nailbertan1620 I had the cardioversion but they gave me propofol, it was okay, no effects at all from the propofol I just felt sleepy and fell asleep.
Does that happen due to anxiety attacks? When I get a bad attack I heart rate goes up to 166 or so... then it goes down once I calm down or take a benzo.
no, this is most likely a re-entrant tachycardia. given that she's female is statistically more likely to be an atrioventricular nodal (AV node) re-entrant tachycardia. One might argue there are small notched in the T wave in lead V1 on the tachy EKG suggesting retrograde atrial depolarisation. If that is the case the AV has an extra pathway which is allowing electrical signals to go round and round in a micro-circuit which repeatedly stimulates ventricular contraction. Adenosine temporarily causes AV block by increasing potassium efflux in the specialised heart cells which creates a state of hyperpolarisation meaning that those particular cells in the AV node cannot be stimulated and subsequently breaks the circuit restoring sinus rhythm. Beta blockers, which he mentions in the video, will help to keep the AV node a little dulled down to reduce the chances of this happening again. sometimes, the only definitive treatment is for electrophysiology studies and catheter ablation, which is a procedure that maps the electrical signals within the heart, locates erroneous cells and destroys them (usually with radiofrequency ablation). anxiety can cause a rise in heart rate but this is usually down to stress hormones, some of which have sympathomimetic properties which increase heart rate. Adrenaline is one example.
I had three episodes of svt in March. On April first I had a sv ablation to fix the problem. Adenosine was administered all three times. My heart rate is still above 100, at times 125 bpm. I wonder, what can cause this to happen and what are the chances of this happening to me again? Oh yea, love your videos, I subscribe to your channel. Was wondering too,
omg, watching this gives me bad anxiety. i have a type of tachycardia (i don't know how to translate it properly, sorry, it's a "harmless" type, but really super unpleasant) i had a cathether ablation in 2012, but occasionally i have milder "attacks" (before, i was at about 220 bpm, now it only goes up to 130/140, but it still feels awful)so, watching this poor patient sit there with that high a pulse stresses me out ^^; nice video and explanations, though, i liked the info and the voice of the doc was really sweet, too.
a catheter ablation doesn't really help they try not to do them much anymore at least that's what my new car. Ologist said when I got a second opinion about the other doctor wanting to do a ablation the doctor said that new studies show it don't really help and some times it makes it worst
i had svt 189 bpm 2 infusions of adenosine didnt work and infusion of flecanide didnt work either, where about to reverse me to sinus via shock but reverted by then
I had it given to me and it felt like an elephant was sitting on my chest. My entire body was on fire and I couldn't breathe. But then it passed and my heart calmed. The result was like magic but those 5 seconds felt like hell on earth.
Wide complex, premature beat with a high T wave? Yeah, that's a PVC. Could be caused by hypoxia if the blood pressure is low. But I don't think the BP was low because they wouldn't be doing this if the patient was unstable.
@@jessealtamirano3931 its a single premature ventricular contraction during adenosine administration. the exact cause is unknown, but ectopic beats are completely normal and every human on earth gets them. ectopic foci can lay dormant because a normal heart rate keeps them refractory, but the administration of adenosine causes AV block, thus inhibiting ventricular depolarisation. this in turn may give rise to an ectopic foci in the ventricle being able to fire. it could also be reperfusion related. the first ECG clearly showed global T wave inversion hinting at sub-optimal perfusion in the myocardium. the heart is working overtime at 200bpm, filling time is reduced, reducing cardiac output, potentially lowering diastolic pressure to sub-optimal levels (coronary arteries fill during diastole, not systole). with reduced oxygenation, free-radicals can build up and the sudden reperfusion on restoration of sinus rhythm can cause temporary reperfusion irritation. it could also be totally random and it was just an incidental visualisation of a perfectly benign ectopic.
This just happened to me. We couldn't pinpoint the cause but I had to get a double dose of adenosine and it was brutal. But my ER docs and nurses did the same thing.
Actually SVT can cause a heart attack because when the heart is beating at rates that fast it can cause heart failure also trigger blood clots to get loose and travel within the body and can even cause a stroke if not treated quickly. And yes it can come on randomly to anyone at anytime even people with no cardiac history.
I don't drink soda. Had horrible back pain, decided to take Exedrin as narcotics make me nauseated. 4 hours later, ER for SVT (worked great on my back...not so good on my clunky ticker LOL)
yes a bit but I have found that rapid afib generally does not go as fast as an SVT, where SVT is usually mininum 180 - 220 bpm and afib is irregular, unless it is an a flutter
svt is diagnosed by a proper 12 lead. They look at the rhythm of the chambers of the heart. The doctors in the video weren't cardiologists, but any cardiologist looks at that strip of paper from the ekg and knows.
He summed up adenosine perfectly i had it done twice worst experience ever i thought it was going to kill me guess what? It didn't work after 2 goes they wanted to do it a 3rd time i said "no way" they sort of rush it through you with water you go into a spasm its awful they then put me on a drip which slowed it down eventually mine was 260 bpm since then ive had an ablation and not had it since 😀
Cool video , but at the end , the ECG seems to show a LBBB , is it there or , what is up with the notched R wave . thanks for these videos a great educational material that drives a point home .

You have WPW syndrome. Turns out that's more common than people know. Your heart has extra pathways which could cause arrhythmias at fast pulse rates.
@@rifleman1002 yep. Had two surgeries to correct it.
Even after 9 years of this post, this is great for our 911 calls. Thank you for sharing!
I remember those days. My heart would shoot up instantly to between 200-300 bpm. My shirt would look like it was just vibrating on my chest. Most times the episode would stop on its own (I had episodes 4-8 times a year usually), but occasionally it wouldn't stop and I would need the Adenosine. Adenosine caused chest pressure and tightness for me but the first dose always worked. I finally had my RFA surgery in 2012 and I haven't had an episode since! I did wake up in the middle of surgery due to the adrenaline they use to cause the tachycardia. I felt somewhat paralyzed but I could see what was going on. I could see my heart shaking away on the monitors. They got me under again quickly, but it was kind of cool to get to see the doctors working on my heart while I was supposed to be asleep lol!
sounds cool!
Crazy!!🤣
Wow 300bpm, that's virtually a death sentence for most people, medical information suggests people starts dying at 250 depending on their age health condition and body make up everyone is slightly different but haven't seen any concrete evidence of ecg of a heart rate near the 300 I have read it's possible haven't looked for info on over a decade so who knows what's been updated since then
I had this svt 3 times. I had an ablation done and have been good to go ever since.
Similar story here. First two episodes resolved themselves, third time was a trip to the ER and two hits of adenosine (don't remember how much, but it was two injections).
Had my ablation in March just before the Covid restrictions started.
@@nihilvox As im not sure if Anne is still active on her account i'll just reply to you.
I've had 2 SVT (AVNRT, to be specific) episodes that's ended up with an ER visit. Other than that i'd say about 5 ish that resolved themselves within a few minutes. Had an ablation in either late march or early april 2019. January 2021 i suddenly got another AVNRT episode (2nd ER visit) because as it turns out i had 2 reentry circuits and they missed one. The EKG from the ambulance showed 258BPM at the highest but it was hovering between 245-250 mostly. I did not have to get adenosine as it calmed down about 3 minutes before arriving to the ER and i was somewhat stable with sinus tachycardia at around 120BPM instead. Going to have a followup december this year and schedule another ablation, only problem is my 2nd reentry circuit is believed to be very close to my av-node so the risk of me ending up with a pacemaker is higher than the previous ablation so im nervous as hell.
@@nihilvox how are you doing now
Anymore svt episodes
@@DerpsterSwe how did it go
First time I ever took that fun trip on that magic rocket ship running through the sky, 185...Thought i was dead 😂
I was taught in nursing school that carotid massages are not commonly practiced anymore. If there was an atherosclerotic plaque in the carotid artery and you massage it loose the patient is at risk for a CVA.
I was once in the hospital for fast heart rate they asked my mom if I had to be shocked or if I had to have denizen they put the pads on me just in case they had to shock me but they didn't .my mom told them that I had to have denzien
Denizen? You mean Adenosine?
There are other ways to massage the vagus nerve. That's just one way. It could happen I've heard of that happening then causing strokes.
Well yes and no, I mean, what are the chances? However HR must go down by all harmless means before flushing adeno.
@@austinwiles4846 Cool story, bro.
I would love to watch more videos like this. It greatly aids me in my preparation for the nursing Nclex exam. Being able to observe how things function in real-life situations is invaluable. It truly brings me joy to witness the Medical Team saving lives. Well done, everyone! ❤🥳👏
I am currently learning about this. This visual helped a lot, thank you so much!
I used to LOVE the warm fuzzy feeling of
I'm really enjoying the more advanced videos mixed in with the more "fun" entertainment ones (namely abscesses), it's great to see cardioversions actively occur.
This has got to be the coolest thing I've seen. I've actually had SVT once, but my BP maxed out at 180 bpm. After an hour or two, the rate went down by itself. I was 18 at the time.
@@bopsandbangers Yes. I know the cause and avoid.
@@bopsandbangers It's scary to say the least. Yes, caffeine can do it. Sometimes it can happen with other medications. Just to be safe, make sure to follow-up with your doctor. As long as I avoid my trigger, I don't have a problem. ;)
Cool? Don’t quite know what to say about that comment.
The only warning was from who I assume was a nurse that it’s going to make you feel “ weird?” Fortunately I watched enough of these to know better but if somebody administered that to me without warning, you calling security instead of the crash cart.
Wow 205 bpm! I recently had pneumonia and went to the doctor for that and she told me I had a very high heart rate (156 bpm) and she was concerned something was very wrong, one thing led to another after that was flushed out with saline, I was put in an ambulance and transferred to another hospital after they gave me a med to try to lower that and it lowered to 37 bpm and bp 60/30, at the other hospital they did a cardioversion and that fixed it but I was in the ICU for 4 days. Turned out I have a mitral valve prolapse that should be repaired, sooner than later. I had no symptoms at all with the 156 bpm and it was probably going on 1-4 weeks with the pneumonia.
248bpm was my highest recorded heart rate, I had it undiagnosed for 28years and so it was a long adventure average was 220bpm during a svt episode
A-Fib is no joke. Family history, clotting distorder, etc. Odds are not in my favor. I had first hand experience with Adenosine this past fall after a stroke. I was in A-Fib on the CC Bus. BP was about 160/120s & P was in 180+. When that Adenosine gets in your system, you literally feel like a yo-yo. Like someone pulls your heart out of your body and slams it right back it. Like a roller reaching the peak and then going down the bottom. It hurts! REALLY. It truly hurts. Patients should be administered pain meds every time cardioversion is done and they're awake.
... Well I didn't feel any pain,
Very interesting how different we all are
What clotting disorder do you have?
You are lucky because adenosine should not be given for A. Fib it can lead to a leathel rythm.
@@jessealtamirano3931 my thoughts exactly.
Yup!! Been there!!
Good job on warning the patient about the awful feeling
To be honest when a person who has this says it doesn't work believe them and help them as soon as possible. I say this because I know I will try everything in the book before I call for help and when I call for help it is already too late. Although doctors may not see the urgency in this it is very scary and frightening. Your heart is making hormones shoot off and it causes you to stress out like crazy. So those hints he is telling her should wait until she is stabilized. IMO I have SVT and I have an ICD. I also had ablations
roblou62 Maybe she's new to this.
I try vagal maneuvers for 10 minutes, then go to ER... and tell them I already tried for 10 minutes ;)
How many ablation have you had? I had to have 3 before I was ok and didn't have them any more.
Why the ICD? Because of the SVT?
Doctors and nurses are soo amazing thank you guys for all you do!
i recently had a rate of 229 and after drug it went down to 62 then up to 110. that feeling when you 'reset' wow. nurse said to me its like impending doom like im going to die, they were true but wow i felt the blood rush back to the rest of my body and felt 80% better. now just waiting to see when i can have an oblation. fingers cross soon.
The feeling is because, when the heart beats so fast it barely pumps any blood.
Ablation
I am about to have my surgery for this SVT
I had ablation. Not a single episode since. Do it.
My count of the times I've had Adenosine I lost count at 35 I have Brugada Syndrome and I have had SVT because of this since I was diagnosed at age 4 I'm 21 now and tired of the arrhythmia, Ablation doesn't work and I have an ICD now
Hey think of it this way, if you where born 100 years earlier you would have like 0 chace lol. So your pretty lucky to be alive today. Idk maybe that came out negative im just tryna be positive 🙃
Quick story about my initial experience with Afib.
Few years ago I went to Cuba with a couple friends - two of them work in Emerg; great doctors.
Long story short, I overdid it with the binge drinking and senioritas. One last debauchery, is what I thought to myself. BIG mistake. I was well aware of the fact that this kind of Reckless Behavior could potentially trigger an arrhythmia, but I never thought it would happen to me.
We flew back home, went our separate ways.
That night I felt extremely dehydrated, and very anxious from the glutamate rebound, worst hangover of my life.
Few hours later as I was eating pizza, I felt a flutter, then the tachycardia set in. At first I thought I was going to die, then I thought to myself, if this was extremely serious, I wouldn't be cognizant, of anything, I'd be dead.
I composed myself ,went to the hospital. White T-shirt covered in pizza sauce, hyperventilating etc. Not a good look.
The nurse gave me a quick EKG, I was in AFib. A few seconds later the emerg doctor walked in, looked at me and asked me: Adenosine or C-version? I chose adenosine.
I wasn't ready for this Beast, never again. NEVER. The feeling of impending doom, is real.
I tip my hat off to any individual who has been administered this drug on more than one occasion.
By now you probably figured out that I work in the medical field.
Here's some simple advice to anyone reading this for whichever reason:
Treat your heart with respect, eliminating all behaviors that lead to heart disease is paramount. It's an incredible/fascinating organ. ❤
Hello, Cedric. Similar story here as I have afib and alcohol triggered my first in 2017 after a weekend of binge drinking with friends. It started on monday right before sleep after a normal day and I knew those parties were the cause when the ER doctor said it seemed to be a "holiday heart syndrome" case.
Recently I had a second episode. Those familiar weird palpitations woke me up - no apparent reason by the way - and I went to the hospital extremely calm and already certain about the procedures I might be submitted. Rapid afib confirmed and this time they decided to give me adenosine. No questions asked. First a shot of 6 milligrams, then 6 more. When that drug hit me I just panicked. By far the worst feeling of my life. It was like a near death experience. The doctor had warned that patients usually describe it as a roller coaster ride, but it's way worse.
So in your case I supposed it worked, right? It didn't for me after all that. It kept me thinking though that adenosine shoudn't be prescribed for patients with atrial fibrilation, but what do I know?
Cedrick Roy now would you chose the c version over adenosine?
Love videos like this. If I could go back in time, I would've went to med school instead of engineering. I would specialize in electrophysiology.
I'm thankful that I am able to self revert will valsalva... I almost had to go to the hospital but a nurse friend of mine had me out my face in Ice and breath, then did a jugular massage and it reverted. 👀
wow. this is just awesome. now i can feel less afraid of my heart rate going to 130s. (only when i exercise, i have a healthy heart)
This lady is a trooper!! 200+ bpm!! I’d freak out! Shoot I freak out when it go to 180bpm 😫
My SVT record is about 302bpm
Howl yourg OMG!! 302!! I can’t Imagine how that felt! I would be passed out because at 180-199 bmp I felt like I was going to pass out. Thank god you’re ok 😊
I had Brugada Syndrome and it caused my SVT episodes I lost count of having Adenosine at 35 times and I am now 10 months post transplant
I was working on the helicopter(I'm a flight paramedic) when that episode happened, I suddenly felt really Ill then my ICD shocked me so I asked my coworker to run a 12 lead and the defibrillator could barely register my rate it was so fast so they put an IV in and gave me Adenosine with NO Sedative because I usually had low blood pressure and let me tell you it feels absolutely horrible having Adenosine with out a sedative
Howl yourg WOW! Talk about being at the right place at the right time!! I’m so happy to hear that you’re ok! What transplant did you have may I ask?
Had problems with this in the past - 1960’s and 1970’s - treated effectively by an aramine drip. I recall the feeling of relief the instant the drip “kicked in” and halted the arrhythmia.
Just in case anyone wonders a little bit more what it feels like and maybe a funnier way of thinking about Adenosine, I had to take it last year right before Christmas because I got an svt episode lasting about 4 hours and I finally gave up and when to the emergency for the first time (Good thing, too, cuz that set me on the road for the wonderful catheter ablation that cured me

This was Awesome! Thanks for helping with my Paramedic School homework 😂
So...the doctor is requesting the patient to bear down in order to increase intrathoracic pressure also known as the Valsalva Maneuver. In response to the increase in pressure, the body's parasympathetic nervous system responds and increases in activity. The subsequent increase in parasympathetics slows down the heart rate, providing rate control in a patient with SVT. There a whole host of maneuvers that are non-invasive and are at the disposal of healthcare providers when a patient is in SVT. Most of the time, patients require more intensive intervention such as chemical cardioversion (w/ adenosine) or cardiac cardioversion with a defibrillator. The key is the "increase in parasympathetic activity, which slows down the heart rate." Theoretically, anything that accomplishes this could be attempted.
chargerpride123 Bearing down hardly ever does it for me. Dunking my face in ice water, sometimes. Usually what works is gagging myself with my fingers...and even that takes a few tries. I was told NEVER to massage my neck, as if done wrong can lead to asystole.
If vagal maneuvers don't work on my own after 10 minutes, then I go to ER
+Julia Despain It wont lead to asystole, it could throw a clot and cause a stroke in an older patient. Asystole is noted as a flatline on ECG with no electrical activity in the heart. That's not going to happen by massaging the carotid artery in your neck. 12 mg adenosine worked for me.
I always needed 3 shots to correct the episode. I would wake in the night when an episode came on. I’d get dressed without waking my girl and drive myself to A&E. I’d get reverted and rest under obs for hours then head back home and rest before she woke. One time I drove myself there and didn’t make it inside in time. I collapsed in the car at 3am and was found by a guard. That was the end of self drive care.
Good drug. When your lay there in a hospital bed with a heart rate at 240 beats a minute. Nothing else has worked. This did work. 6 hours later I was asleep after it was decided I should stay in hospital and my heart kicked off again. Best thing to ever happen cause the doctors worked out in a moment what had twiggered 2 svt episodes so close together and I've not had a problem since
My daughter was born with Wolf Parkinson White syndrome. She actually was in a breakthrough at birth, delivered by emergency C-section. At that time, open heart surgery was the only method of finding the extra pathway. After 15 years of using adenosine, vehicle maneuvers, and electrocardioversion, she was able to have heart ablation using intervenous methods. I'm very interested in WPW - have you ever had a patient with WPW? And how did you treat it?
Great doctor.
What you have to be careful when using this drug is that the rate you're seeing is not a compensatory rate due to an underlying problem such as PE.
wow the way he explained it to the patient was amazing !
I have SVT but my heart has gone faster than that
Mine has gone 300 beats per minute
I have had SVT since I was 6 months old
300? Do you have heart damage from that? Cause I thought at that rate it's already a heart attack because of the heart isn't filling with blood!!
May I ask how old you are?
@@azmagaref I don't have heart damage from that and I am 12 years old
@@bxngtanbby9681
You're very very young that's probably why your heart can beat that fast without major problems.
I wish you a healthy future.
@@azmagaref thank you
Great learning video. ACLS student
I may not have noticed, but what was the patients blood pressure? (if you can remember of course) :)
what are the long term effects on the heart with svt for some one like me that have it do to my nodes causing my heart to miss fire?
This is really late so you may have found your answer already.
The heart has 4 chambers, atria are the top 2 chambers and ventricles are the bottom 2 chambers; both are given electric signals in order to squeeze blood.
SVT is short for supra (above) ventricular (ventricles) tachycardia (fast heart rate), a condition where something above the ventricles of the heart (the atria) is beating very fast due to of rapid firing of electric signals. This causes the heart to pump faster than 160 beats per minute-the average is generally 60-100.
The heart isn't designed to pump so fast for so long and it'll eventually tire itself out, causing the heart to possibly go into V-fib (ventricular fibrillation-where the ventricles start to seize instead of pumping blood) and/or shut down.
@@tiffanyh629 I had this to happen recently, and so when my heart rate wasn't going back down after hours of this, I went to the ER. On top of this, I have had a prolapsed mitral valve for years. Also, in between jobs currently, so no health insurance. However, I am very grateful to still be alive!
I had 3 SVT attacks today in a one hour period. Very painful and felt like I was gonna pass out. I was given adenosine in my 3rd trimester 7 months ago. My heart rate was 230. It is a very scary feeling having that drug pushed when you are pregnant. I have had problems since I was a teen and have been on inderal since I was 18.
Are u ok now?
Your lucky I'm 21 and my heart rate has beaten 300 a few times
Hi can anyone help me, I’m 18 year old girl skinny healthy weight- my bpm is always around 80-105 while sitting down or resting while I’m walking it’s 100-140 while running for a short period like 3 minutes it’s 160 I get chest pain arm pain and extremely out of breath any ideas on what it could be
First stop worrying too much because it's probably your worrying that's making it a little fast, you are very young and your heart is doing it's job of beating. Might be a little fast but nothing major.
Let your GP send you to a good cardiologist for stress test, ultrasound and an overnight holter monitor attachment.
He might decide to put you on beta-blockers that slow the heart if necessary.
But if you're an anxious person then this is anxiety related.
The rest,walking and running bpm is normal but the chest,arm and out of breath is not. Tell your dr about this
Hope you’re feeling much better
i saw one of theses today, was great hence i came to follow up with a video. thks

@@evesdrop1982 I couldn't breathe after a few doses. It was scary.

I was taught not to massage the carotid because you can break off a piece of plaque and cause a stroke. Is this true?
Ugh I wish, I had to get that shot 3 times in a row, so I refuse it now :( trying to get an ablation
what did the medicine feel like i almost had to take it
It makes your heart stop and start, so it makes your arms and legs super tense, and you feel like you cannot breathe
+demondwells1ns1de that must really suck glad i didn't have to take it
yes it really really sucks, I wont allow them to give it to me now
For me it feels like my whole body goes very weak for a quick minute like a rush u can feel the heart restart in ya body it’s so weird and scary !
Thank you for the videos! I dont see this kind of stuff since I work in family health...
Does that happen due to anxiety attacks? When I get a bad attack I heart rate goes up to 166 or so... then it goes down once I calm down or take a benzo.
no, this is most likely a re-entrant tachycardia. given that she's female is statistically more likely to be an atrioventricular nodal (AV node) re-entrant tachycardia. One might argue there are small notched in the T wave in lead V1 on the tachy EKG suggesting retrograde atrial depolarisation. If that is the case the AV has an extra pathway which is allowing electrical signals to go round and round in a micro-circuit which repeatedly stimulates ventricular contraction. Adenosine temporarily causes AV block by increasing potassium efflux in the specialised heart cells which creates a state of hyperpolarisation meaning that those particular cells in the AV node cannot be stimulated and subsequently breaks the circuit restoring sinus rhythm. Beta blockers, which he mentions in the video, will help to keep the AV node a little dulled down to reduce the chances of this happening again. sometimes, the only definitive treatment is for electrophysiology studies and catheter ablation, which is a procedure that maps the electrical signals within the heart, locates erroneous cells and destroys them (usually with radiofrequency ablation). anxiety can cause a rise in heart rate but this is usually down to stress hormones, some of which have sympathomimetic properties which increase heart rate. Adrenaline is one example.
I had three episodes of svt in March. On April first I had a sv ablation to fix the problem. Adenosine was administered all three times. My heart rate is still above 100, at times 125 bpm. I wonder, what can cause this to happen and what are the chances of this happening to me again? Oh yea, love your videos, I subscribe to your channel. Was wondering too,
you have to take a beta blocker. i had to have a double dose od adenosine. first time didn't work
I just had this done a few hours ago. What a weird unpleasant experience but it worked.
205 is terrifying 😮
omg, watching this gives me bad anxiety. i have a type of tachycardia (i don't know how to translate it properly, sorry, it's a "harmless" type, but really super unpleasant) i had a cathether ablation in 2012, but occasionally i have milder "attacks" (before, i was at about 220 bpm, now it only goes up to 130/140, but it still feels awful)so, watching this poor patient sit there with that high a pulse stresses me out ^^;
nice video and explanations, though, i liked the info and the voice of the doc was really sweet, too.
a catheter ablation doesn't really help they try not to do them much anymore at least that's what my new car. Ologist said when I got a second opinion about the other doctor wanting to do a ablation the doctor said that new studies show it don't really help and some times it makes it worst
When this happens to me they always admit me to the hospital for 3 days
God Bless The Doctors ,,,,,
Cardioversion at 2:44
Would love if you can teach on ecgs
uh, excuse me, a heart attack, without even knowing?
i had svt 189 bpm 2 infusions of adenosine didnt work and infusion of flecanide didnt work either, where about to reverse me to sinus via shock but reverted by then
Thank you!
great video doc.
It didn't hurt at all when I had this done. I only had a few moments of feeling light headed.
(I have been told I have a high pain tolerance.)
I had it given to me and it felt like an elephant was sitting on my chest. My entire body was on fire and I couldn't breathe. But then it passed and my heart calmed. The result was like magic but those 5 seconds felt like hell on earth.
Thanks doc! Very interesting
When I was in hospital I use to have heart beat fast
thank you , so the manoevre dont work, but 6 mg of adenosin iv work and you do what after , lopressor ?
Thank you for your help
Why the sporadic beat at 3:30 have different morphology of QRS complex?
This is a PVC?
Wide complex, premature beat with a high T wave?
Yeah, that's a PVC. Could be caused by hypoxia if the blood pressure is low. But I don't think the BP was low because they wouldn't be doing this if the patient was unstable.
+SHJ Gaming I think so.
The heart is irritated my the cough medicine that she took. That in its self would cause an irregular beat.
@@jessealtamirano3931 its a single premature ventricular contraction during adenosine administration. the exact cause is unknown, but ectopic beats are completely normal and every human on earth gets them. ectopic foci can lay dormant because a normal heart rate keeps them refractory, but the administration of adenosine causes AV block, thus inhibiting ventricular depolarisation. this in turn may give rise to an ectopic foci in the ventricle being able to fire. it could also be reperfusion related. the first ECG clearly showed global T wave inversion hinting at sub-optimal perfusion in the myocardium. the heart is working overtime at 200bpm, filling time is reduced, reducing cardiac output, potentially lowering diastolic pressure to sub-optimal levels (coronary arteries fill during diastole, not systole). with reduced oxygenation, free-radicals can build up and the sudden reperfusion on restoration of sinus rhythm can cause temporary reperfusion irritation. it could also be totally random and it was just an incidental visualisation of a perfectly benign ectopic.
liam watters so basically what you’re saying in that long paragraph is it could be caused by a lot of things. I agree
I had chemical cardeoversion once. It did not work.
This just happened to me. We couldn't pinpoint the cause but I had to get a double dose of adenosine and it was brutal. But my ER docs and nurses did the same thing.
i had a double dose too. im 25 years old
Amazing
TY FOR YOUR VIDEOS DOC.
Can svt cause a heart attack??? In a 23 year old and can svt just come on with no trigger just randomly
Guadalupe Salazar it is always comes randomly.It wont cause any problems unless you are 80 years old or have a serious heart problem
Thank you :) helps a lot im just pretty new at the whole thing
no problem!!!!!! Im glad i helped !!! Dont worry and everything's gonna be alright !
Actually SVT can cause a heart attack because when the heart is beating at rates that fast it can cause heart failure also trigger blood clots to get loose and travel within the body and can even cause a stroke if not treated quickly. And yes it can come on randomly to anyone at anytime even people with no cardiac history.
@@nailbertan1620 Thats AFib.
I have had 2 cardiologists tell me that it cant cause a heart attack. It can damage the heart over time if not treated.
Should remember push synchronized mode when paitent arrythmia is not VTach/orVFib. Shock between QRS-T in SVT makes idiopathic VTach....
Had adenasine 5 times in a row in less than 10 minutes it hurts
Very interesting, drugs never work for me! It's always cardio versions
Angela Raymond this is also a cardioversion. One is a chemical and one is a electrical.
Never ceases to amaze me
How often in practice do you see the carotid massage work?
i wish if they have a cure for psvt
They do, its called cardiac ablation. And it works great.
Was there any signs in the further tests that this patient suffered a heart attack, during this episode, or was it all ok? Great video doctor
Why did the Robotussin cause these symptoms? Did she have an underlying disease?
In nursing school now/studying cardiac.
Christine Teeples Most cold medications stimulate the heart.
I don't drink soda. Had horrible back pain, decided to take Exedrin as narcotics make me nauseated. 4 hours later, ER for SVT (worked great on my back...not so good on my clunky ticker LOL)
It could have been a medication interaction, too.
i suffer from SVT and usually get them during orgasm or anytime my endorphins over react. Even a simple little itch can set it off.
hifiguy9 I only get it when I am Sitting or standing still, really interesting
Then stop having sex.
Holy crap that sucks. Imagine being afraid to feel really happy
Is it just me or is it hard to differentiate between rapid afib and SVT?
yes a bit but I have found that rapid afib generally does not go as fast as an SVT, where SVT is usually mininum 180 - 220 bpm and afib is irregular, unless it is an a flutter
svt is diagnosed by a proper 12 lead. They look at the rhythm of the chambers of the heart. The doctors in the video weren't cardiologists, but any cardiologist looks at that strip of paper from the ekg and knows.
He summed up adenosine perfectly i had it done twice worst experience ever i thought it was going to kill me guess what? It didn't work after 2 goes they wanted to do it a 3rd time i said "no way" they sort of rush it through you with water you go into a spasm its awful they then put me on a drip which slowed it down eventually mine was 260 bpm since then ive had an ablation and not had it since 😀
Cool video , but at the end , the ECG seems to show a LBBB , is it there or , what is up with the notched R wave . thanks for these videos a great educational material that drives a point home .
this does not meet left or right BB criteria.
Nope, go back to school.
Love svt
What caused there heart rate to go up so fast?
For me dehydrated
Lots of thing can cause it.
Wow From 200 to 77.
Its very dangerous to do caroitd sinus massage at home
They gave me 3 doses of this medicine and nothing
