What an enlightening coincidence. Six years ago today (2/17/14), I had heart failure and an urgent need for someone to help me understand exactly what the heckledoodles had happened to me. In your video above, you have FINALLY given me the explanation I've needed for the last six years! Kudos to YOU and poo-poo to my doctors back then. Thank you!
Being able to teach such complex subjects so well is a gift. Thank you Dr Seheult.
I've started working as a cardiac nurse and I find your materials really helpful and easier to understand! I will share this to my colleagues, keep it up!
I have CHF after a life changing car accident. I had cognitive issues very bad. My arms swelled and they didn't figure it out for along time.(6 years) I do have chronic pain as well. I was at 33% heart function and started to lose weight quickly and i was sick after eating. Thats how they figured it out. My blood pressure was all over the place. Been on meds for one year exactly. And i have improved by 10%. I got rid of toxic people in my life. Eat very well. Try to do movement everyday as best i can with the chronic pain is challenging, But i manage. I also meditate and enjoy peace. Been a game changer. Thank you for this video. It explains well. 😊
His voice sounds so kind and compassionate. I Thank him.
I was 'told' I had CHF.. but recently a Doctor told me that my numbers where improving, that he had NEVER seen anyone's numbers improve.. this without any bypass or such, I take only blood pressure meds.. and NOT any Beta-Blockers as those are toxic to me.. I've been taking Herbs and doing Chelation treatments.. So, this 'it' can't be fixed thing is poor judgement..
I'm returning to my nursing degree - these lectures are fantastic for giving a no nonsense, basic language foundation for making the in depth information much easier to understand
Thanks for the feedback
Thank you for a good presentation, No music, no robot voice, no cartoon characters.
Well done.
Absolutely brilliant. Explained in a manner that makes the topic easier to grasp and clarifies many key areas. Invaluable resource.
Once again, you have clarified something that had been confusing me for a while in patient documentation, THANKS!
Thank you for helping me understand my husband's condition. You have made it easy for a non-medical person to get the basics. I now have a better idea what questions to ask his doctor. ( I had to sit through several videos that were not as understandable. Thanks again!)
What a clear, concise thorough explanation by Dr. Seheult. He is so amazingly low key but he is able to impart the material in a very comprehensive manner.
Thankyou for getting Jeff Goldblum to narrate this for us, was very relaxing.
awesome! nobody ever clearly explained this to me. I've always had a hard time understanding when it comes to Cardio. Your video helps a lot! keep it coming. BIG THANK YOU :)
+Duangsuda Siritheerawat You're most welcome- thanks for the comment!
You are amazing ! I am a medical student and finally I understood what s going on with heart diseases . I wish my teachers would be like you ! Keep doing that excellent work !
A few months ago I was diagnosed with CHF. I knew what it was started nursing training years ago but family problems stopped me. Thank you.
I want to thank you Dr. Seheult for your many lectures. I am a Paramedic that continually studies to stay current on ever changing trends in medicine. Your lectures have proven to be very valuable with respect to my practice. As you know, Medics must have a working knowledge of many diseases, disorders, etc. We all have certain protocols that serve as treatment guidelines but I want to know more about "why" a certain path is better than another. Your lectures help in that respect.
Regards, DocNaBox55
Good to hear, thank you for the comment
That's the problem. Just enough info to define the problems and earn a degree, cures and recoveries are bad for business. Helpful information is rare and hard to find.🚑💉💊📋📉👻🏆📊💙 sorry about the outburst. Not directed at you, just had to rant. Best Wishes, Al B. Flatlining
Okay what do you do (suggest ) to your patient to get better? What type of exercise, medication or supplements can help one's heart perform better? Thank you
Explained logically and in a simplified manner.
I'm a nursing student and your videos have tremendously helped me through patho and med surge . Thank you 👍🏻
***** Good to hear- thanks for the feedback
wonder if you ever became an RN??
Oh my goodness thank you sooooooooo much!!your explanation is by far the best I've seen. Thank almighty God for this video You really saved me with this assignment I'm doing.
Really enjoy this channel, things are explained in a more simplistic way that you can remember without being too technical. Keep it up guys!! it's much appreciated, I've learnt so much from these types of videos :)
Thank you!
Hello and thank you so much for sharing your knowledge, may the universe pay you back. I am an End of Life Nurse that work independently live in with my dying patients. I will like to explore management of symptoms at the end of life for Heart Failure clients. All of them by now had a DNR/DNCPR. Thank you so much
Thank you so much for this.
My mum is currently in hospital. She was literally drowning in her own fluids as the diuretics were no longer working.
As a result of this she suffered fluid overload and could no longer breath.
Today a chest tube was inserted to release the excess fluid and she is feeling a whole lot better.
Heart disease really sucks :-(
How much EF does she have now? And how many years she been Living with heart failure?
LOVE the traffic analogy!
I'm in nursing school. you give a very descriptive summary of this topic. it's really helping me to understand fully
Aneshia Johnson Thanks for the feedback and best of luck in nursing school

This is the best I've ever seen and clearly explained.....
I wish someone create these utube videos into DVR's so we could keep them and watch then whenever we want..
Thx...
💚💚💚💚💚💚💚
You can download the videos with the right browser extension with Firefox.
It is an amazing skill to be able to explain such a complex process in a such an easy manner…Bravo!
Enjoyed the lecture and appreciate the clear, concise explanations rather than getting overly technical in the language.
RJ Dilts Thank you for the feedback - we appreciate it
Am a retired Dentist with multiple heart disease: inherited from maternal & paternal side. Great review to understanding symptoms, causes, & role of the meds am on.
My dad had heart failure he had to were a life vest take a lot of meds now his heart back to normal
How did his heart get back to normal with CHF what did he do?
You're amazing! Never have I seen an easier explanation.
thank u so much , my medicine quiz is tomorrow and ur videos saved my life
Thank you for just a wonderful explanation on this! It was so informative to me. I often wondered about all the terms I have heard about this subject. Very clearly explained by you. Thank you for this video . Keep up the wonderful work.
thank you! i use your videos to study for my pathophysiology exams
Clear and concise explanation. Thanks! Would like hypothyroidism series.
A few months ago I went to a cardiologist had a ECG and he put me on Carvedilol, Clonidine and Aldactone I have diabetes and high blood pressure and CVI stage 5 and coronary arteriosclerosis and sleep apnea but the cardiologist didn't tell I have heart failure but my vascular surgeon said my heart diagnostic test showed I do but he put it on his notes that I have chronic heart failure
Good job, Doc. Very informative. On Sotolol now for Afib. Ankles swelling. Mild HTN. Also retired from San G. Wish I could have learned some of these things in my younger days. Have patience and teach ignorant nurses like me; we weren't taught these things in school. Great job. Mike Bryson RN
Nurses are taught these things lol what are you talking about? Maybe not back when you were in nursing school. That or you weren’t paying attention.
Pls do not use dark blue ink in a dark background. It is hard for the reader to read the text in blue. Thanks for your amazing presentation, Dr. Sheultz
You are right (explaind clearly) ..and as they said plz explain cns topics u r a good teacher ..love from saudi arabia ❤️
.
Thank you, the best channel in this field
SolidusSnaaake Thank you for your feedback
Well done- though I don't see four chambers in you valentine, the lecture is pure gold!!!
Amazing video....so well explained. Brilliant.
Very well done presentation. Can be understood even without medical knowledge of medical terminology. Thank you. Very easy for the Layman. Which would be me.
EXCELLENT!! I have viewed several of your vids online, have used some of them as required inervice training, THanK YOU sir!
Excellent and concise explanation.
Can you do a video on coronary artery disease. Please.
You made it simple, thank-you!
Brilliant,as usual.Looking forward to the next one!!
More sense and information than my GP gives me thankyou
Living with heart failure.This is so true!
Scary. How do you cope with it. I have a feeling that I may have it.
Goodness, thank you for this video! You made it easier to understand. God bless
That was a good explanation, i like the way you keep it simple, thank you for sharing.
+Jesús Alberto González Cañas Thanks for the comment!
Ur the best from all the rest ❤️🙏👌🏻
Excellent explanation for this condition
Great explanation! Well structured and easy to understand.
Thanks for simplifying heart failure
I have tricuspid regurgitation and my heart skips constantly.. it's getting worse and worse.. hope I'll be ok...
excellent overview. very helpful as I have an EF of 29
Thx Dr Roger very helpful
But can you tell me about your source for the new classification of congestive heart
Thx again
Amazing! Well done!
The cause is just as important as the diagnosis. Heart failure can be the result of blood clots that when resolved, will normalize the heart action.
Ok? Nobody said it wasn’t
Another great lecture! Thank you so much!
that is great .
thank u so much
that make it more easier for me
I actually have an issue with systole & diastole , I was diagnosed with chf a few months ago & im 39 but my stress test came back excellent far as blood pumping to the heart but when my eco lab was done at the hospital it was at a pumping rate of 20 and I was told to file for disability but I’m so confused bc I don’t have a stent & im only on meds and doctors I feel like aren’t telling me anything so confused bc I don’t know what’s next, thinking about getting a 2nd opinion tho’ & thanks for this video 💕💕very helpful
Jimmy S hey, thanks for the response, but my kidneys are fine, just left the doctors office today for 3 month evaluation and doctor says my EF is now between 25-30 since my last eco lab a few weeks ago and now he recommends a difribulator and I suggest NOT! I told him that studies showed in 2011 that 66% of chf patients didn’t really need this device and they were miserable behind getting it, I’ve decided as if today to get a second opinion,,,, meanwhile getting some cardio in, and changing my overall diet plan for the next few months just to see if I get a different number with new doctor but we must be careful here bc lots of doctor suggest this device for money purposes,
However, so sorry to here about your mom ,,, but happy u were there every step of the way bc I’m sure some can’t say that! They actually did a ekg on me but today but said it was only bc they heard something strange with my heart beat but they always tell me everything looks good when they do the ekg, didn’t know that tells them how long I have bc I know only god is in control of that , with faith and changing my lifestyle I’m gonna CLAIM IT, I will push through and live a long time
Finally get it. Your graphics helped me to understand my supposed 'ok' EF yet crappy symptoms. Mine is 67. What is considered perfect? Thank you for such clear explanation. ❤
Hello,
I'm a bit confused as to how a person who has HFNEF has normal ejection fraction. If they are not getting enough blood in, how are they able to get enough blood out to have a normal EF?
Thank you
Thanks! I love your videos, they are really helpful! Could you do a series on the endocrine system? Thanks again!
I wish my nursing teachers could explain things this clearly...
Julie Rogers thanks for the feedback and topic suggestion
Very helpful! Hope there will be more videos about cardiopathology (Atrial Fibrillation maybe)!
And also EKG interpretation!!!
oriana dashi thank you for the comment and topic suggestions
Excellent video
This video of yours is really awssum really helped me alot
really in short minutes you covered a lot .appreciate you.
very good lecture and easy to understand. thanks.
+Phally Un Good to hear- thanks
This video really help me to deliver my report :) my instructor give me a 98% grade. Thank you :*
+Alfonso Tioquin Good to hear!
Very nicely explained. Thanks for the whole channel Medcram.
But can you please use a different color for writing? Like white perhaps. It would make the teaching clear and easy to read.
another good one, thank you...
very good explanation
Well explained thanks doc
i am from Algeria thx a lot
+esma sahbi Thank you for watching in Algeria!
are you ok ?
thank you very much for detaile interpretation of congestive heart failure really it is a tough subject yet your way of teaching was more attractive due to short example as systaly s1 and dysly s2 like contraction and resting face , it is also fact that heart is closed chamber having 4 their main function totally depends on kidney liver .right side of the lung and mainly coronary artery for the proper function of the heart all these need to pay collectively role however the main and primary role which urgently coverage needed is coronary blood supply this is key root for the activation heart chambers all heart complication like submuiral myocardial death and others always associated with it .thanks
Thank you for the clarity. My brother has just been diagnosed with diastolic heart failure.
Normal ejection fracture... but less than a normal, healthy heart, right?
I am 37 and was just shown on my nuclear stress test results that I have Preserved Left Ventricle Systolic Function. So I’m so confused because my EF is 61% and what he said doesn’t add up with my symptoms and what I was told. He said,”So if you have Systolic then you know you don’t have blood getting out.”
So is the heart dr who filled out my test result report right or wrong? He said I have 61% EF but Systolic.
I’m 37 and I have Graves’ disease. I’m so nervous. I can’t breathe good at all. I have three kids. Also chest pain. I don’t want to have HF.
+Brooklynne Sulfridge Ef of 61% is normal. If you have heart failure then it would be “heart failure with preserved systolic function”. Ask your doctor to explain specifically what is going on in your case.
With HFNEF, is it not that the heart cannot relax, which would imply that there was contraction force inappropriately occurring during diastole, but simply that the relaxed heart muscle has difficulty stretching due to its bulk, in other words, this is actually a compliance issue. Thanks.
Did you mean to say Renin-Angiotensin System, or is Reno-Angiotensin System a new terminology variation?
I was told I have heart failure at the moment I only take blood pressure medication and a water tablet and a blood thinner I walk 3 miles a day with no breathlessness no swelling anywhere in my body but they told me my numbers were going up my blood pressure is normal the only thing I stopped eating is salt and meat
Your lectures are amazing!Great explanation. Please do make lectures on CNS topics:)
Thank you! This is really helping me review for clinical rotations!
Under HFNEF wouldn't there be greater focus on L atrium? If a 4:3 ratio easily found on pulse and drop in diastolic do you expect edema both heart and lungs? Normal sinus? When you can see a band and calcified striations above what looks like a "ballooning" then collapse on itself back wall L atrium on ECHO, what would your expected cause would be?
Very easy to understand! Thank you 🙏
Is left ventricular dysfunction defined as left sided heart failure? What about both systolic and diastolic failure Grade 1? Is the Grading of heart failure based on the echo? Is not just a heart impairment? Is diastolic failure Grade 1 normal as we age? And is an enlarged heart "heart failure" or "cardiomyopathy??? Whats the difference between Heart failure and Congestive Heart failure? What if the patient suffers from both systolic and diastolic impairment, but EF is low normal, for around ten years, but suffers breathlessness, lightheadedness upon minimal physical task such as cleaning a mirror? Very confusing when reading the definitions. Aome HF patients are normal active others not so active and limited even if EF is normal, why is that? Thank you.
Very well explained ! Thanks :)
very good and helpful
Would an individual who has persistent a fib with a reduced ef be considered to have heart failure by most cardiologists or is heart failure simply a severe ef?
So, if there is a time-lag with the blood not being pushed out, after it is pushed in, would a stimulant that raised the amount of heart-pumps per minute, help alliviate the problem? I realize your video is old, but, with no real pulmonary issues, except for a PE 10 years ago from a DVT (twice, and BT's for life) has something new arrived since this posting, regarding the heart? I am on personal oxygen to oxygenate my blood, but only use it when my oxy level dips under 90 (it has normally been in the mid-to high 90's, consistently, as measured by the blow test, and now with my own personal oxymeter).
I was diagnosed with HCL (non-Hodgkins), received 40 hours of chemo, back to back (80 hrs. total) with a 24 hour break, and spent the next 12 years in bed, 18 hours a day with chemo-haze. Time out of bed was extreme dizziness.
My diagnoses with HF came at the near end of my chemo-haze; normal chemo-haze usually lasts about one year with most people, and 5 years seems to be a normal, too, but not 12, in my mind!
40 years ago, I failed a flight-physical (FAA) due to gigantic inverted t-waves. Remember, gama and MRI's were not yet invented. Two years ago, and since, my inverted t-waves are apparently gone, as they no longer show up on my EKG's. I recently passed a chemical-stress test, that found NO ISSUES with my system.) (I respect my health, and I try to keep it optimal, because that is what people must do. I've been this way my whole life; but, because of HIPPA changes, I thought I would bounce this question off of you.) (I was born a few years after the end of WW2.)
PS-Thank you from the bottom of heart (no pun intended) for the information you have provided to me and all of your viewers. Oh, PSS, I take my vitals, by myself, every day. If I get a good blood flow for my glucose check, I know I'm taking my thinners correctly and if not, I double-check to see if I missed a dosage, 5 mm X 2 per day. I also have my own Drive BP cuff, and never go out of the green-range. I have just recently been able to take care of myself with no issues, and know that increased exercise will help me, also.
All of this is just med history. If you respond to this, the only question I have, is about a stimulant that would make the heart beat faster, for the entre and sorte of blood through the heart! Thanks, again!.
I lost my husband 6 weeks ago to cardiac arrest I'm lost,no warning no symptoms
🙏❤
Excellent lecture!
Do the contractions and relaxations of the heart muscle depend n any way upon the usual mechanisms. That is upon calcium and magnesium pumps with the nerves serving voluntary muscle. I would guess not but what is the mechanism then ?
Would my ejection fraction be measured and recorded in a normal cardiac examination ? I don't think this is being done, or has ever been, am I wrong ?
Thank you for a very illuminating video; it makes me feel like a prospector searching for gold.
Excellent!
Nice Explanation
Awesome
JazakAllah Khier
I m 32 year old male. My heart is working 22% on 22-10-2018 and presently on 31-1-2019 it is 32%..
how much EF you're having now?
