Thanks for your videos. I am assuming that Oscilloscopes are more sensitive and advanced than EKG machines, yet I can not detect whatever EKG machines are detecting, or maybe I couldn't figure it out. You are experts, can you please tell me how to do it and what I am doing wrong? I also can not understand how the heart's internal currents of AV and SA nodes are detected on the surface of the skin all over the body, please help me to understand.
Never bother commenting on these but geniunely thank you so much for not only explaning the rhythms but giving the best and easiest ways to identify them along with images. Easily the best video on here
@@Suvampaul619 This is a 12 lead EKG, so it depends on the direction of the lead they're reading... That confused me at first too. I don't think I explained it well enough for you to understand, but I pointed you in the right direction to figure out what you're going to need to figure out anyway
As a med student I use these videos to help my studies for courses and they are good for that. But in my opinion these videos are even better to use as a refresher: they are short, to the point and practice oriented, thank you so much!
I am often critical of videos like yours since it is usually very easy to find errors in the presentations. That was not the case here. I might have chosen to elaborate on some points but the video could then easily have increased massively in length. The algorithm brought me here but now I think I'll watch more of your other videos and learn.
@@RhesusMedicine Incidentally, as a student, I met a man who had once been treated for paroxysmal AVJ reciprocating tachycardia by Dr. Wenckebach himself.
What I don't like about ANY videos explaining EKG patterns, is they always show ideal reads. Almost all the EKGs I see are hot messes, that even if it's a pattern I know easily on something like this video, it takes a bit to separate the static from the actual read
In nursing school at the moment, this has made it much clearer what to look for on the graph, the name of the dysrhythmias, and their general causes! thank you so much!
Excellent video! Thank you. Cardiology for me, seems to confuse me as much as math does! I never seem to be able to grasp the concepts, but the light bulb went off for me in this explanation, so thank you lol
amazing video, especially the mnemonic "william marrow". just one feedback: in Germany/Switzerland we say PQ interval instead you PR interval. In this case PQ makes more sense because as you show in 6:56 your interval starts with the beginnin of P and stops at the beginning of Q and not at the end of Q. Thanks a lot and thumbs up for this video
In the US... We call the (Aflutter waves = Large F waves), & (AFib waves = small f waves). Other than that it's pretty good. ✅. Also, with 3rd degree, I've just recently seen were the ventricular rate was in the 60's & 70's , which was cool, but apparently can happen.
If you identify or trace the regularity of the wave, it’s pretty easy to differentiate AFlutter vs Afib. Sawtooth is for Aflutter however it’s might some time be difficult to identify the sawtooth so for me regularity is always final conclusion per se
Aflutter does not always have a (regular) ventricular rate which can be misleading. & You can't have aflutter without a (saw-tooth or shark tooth) configuration. If you are having difficulty viewing the (saw-tooth or shark-tooth) configuration then go to lead (V) & turn the amplitude/ gain up & you will see if there is the (saw-tooth or shark teeth) configuration every time. ✅
Interesting to see how complicated reading these things are. Not being a doctor I watched it out of curiosity. I now know how some of my math and physics students must have felt like. 🙂
Atrioventricular mobitz type I is by far the easiest among all other AV blocks due to the PR segment progressively separation from its QRS complex (ventricular depolorization) every cycle.
My story: One evening I was dozing on my couch while de-frosting my freezer. Suddenly, a huge chunk of ice had fallen from the roof of the freezer and startled me. For days afterward whatever-had-happened had left me with a terrible rumble-like beating in my chest. The wild beats were really strong and unbelievably random. On day two or so I went to my doctor and he immediately wired me onto an EKG machine. It was wierd, cause just afterwards when I'd returned to another room, he listened to my heart once again - and my heart had returned to a normal sinus rhythm, while in the doctor's office ! I wish that I could remember whether he said that it was Atrial or Ventricular fibrillation. He didn't send me to a Cardiologist (I sure as hell would have if I were a doctor), he just gave me a prescription for something called Digitalis or something like that. He told me, he said: " ... It's gonna happen again". I was scared, but it never did happen again. But man, incredibly uncomfortable. That night just after it happened I got on my bike and drove myself up steep hills, I thought that it might make my heart behave itself; of course, it didn't. Great video though, reminds me of tests I had in a Zoology class.
Feedback for the OP: The videos can get even better if it includes less facts (that we can read in books anyways) and more concepts. In other words the videos should try to make topics easier to understand as we study them. u can make the videos in 1.5 speed that way u can squueze a 15 min video to 10 mins and use these 5 extra minutes to give some background info to these facts
Hi, in the Right BBB can you underline or circle where is the M and the W? In left BBB I can see the M and the W but can't figure it out in the Right. thanks
11:55 Sorry, from my understanding from the video, a STEMI found in V1-V4 (anterior chest wall) means a reciprocal depression in V7-V9 (posterior chest wall). However, from the diagram provided, there is instead reciprocal depression in leads 3 and AVF (which are inferior chest wall leads). May you kindly explain this? If not, then perhaps... - Lead 2 (besides leads 3 and aVF) is also an inferior chest wall lead. Why did lead 2 not show reciprocal depression as well? - What are other examples? In this case, anterior vs. posterior. What about findings for the lateral leads (AVL, V5, V6) (where is the reciprocal depression found?) or inferior leads?
Thank you for your comment! 😁 Different sources quote varying definitions, I would therefore imagine there's some leeway as to what's considered significant. As @andrew1234856 alludes to, the percentage will also change depending on factors such as heart rate anyway
My way of remembering BBB is looking at V5 or V1. Then the deflection of QRS if it's pointing down it's LEFT, bec they left heaven, down to hell. Then RBBB is up, they're doing things RIGHT, going up in heaven. 🤣
AT 40 my ECG looked terrible. It was all over the place. Dr did not know why I was still walking. I am 71 now and.I can keep up with my kids at Disney World. ECG is still bad.

Very good and very useful. Non-cardiologists should review this several times.and periodically.
This is great. I wish you had gone into a little more detail and the strips were larger to view but the info is great! -R.N. In the stress lab.
great ECG walk through, would watch again. Thank you very much for this interesting lecture.

Your bundle of knowledge is great and useful but if you can number the series of videos with relevant topics, it will be easy to follow.
Thanks for the feedback - I've tried putting the videos in playlists which may be a bit more organised for you?
Plz make the complete version of this naat... ❤️❤️
Incredible video.
Whoa!!! This is so good! I really like this video! It helps me a lot!! Thaaaank youuuu

Do you have a video for a 6 lead ecg
hope i can pass my internal med exam!
There's a mistake at 4:58. PVCs may be dangerous if they exceed 10-15% of total heartbeats, not 10-15 per hour
Does the percentage change? U can change per hour to per minute and vice-versa?
Thank you for your comment! 😁 Different sources quote varying definitions, I would therefore imagine there's some leeway as to what's considered significant. As @andrew1234856 alludes to, the percentage will also change depending on factors such as heart rate anyway
Do you have a video on QRS axis ?
Not specifically, I do have a video on ECG interpretation that touches on determining the axis
Good video! One mistake though 0:37 it shows the time between P an Q but you call it PR interval (rather than PQ interval/time).
It is called PR because sometimes the Q of QRS is absent or hard to distinguish.
جالب بود ممنون❤
Additionally, you have cool accent 😎
Thanks for this 😂
@@jimmyyyyyyyyyy of course!
Do you have any further information axis deviation
