Thanks for watching. The full ECG Explained Clearly video series by Dr. Seheult is available here: www.medcram.com/courses/ekg-ecg-interpretation-explained-clearly
In October 2020 my Apple Watch Series 5 tapped me on the wrist and indicated it detected AFib. I hadn’t been diagnosed with AFib. I took an ECG and went over to my doctor’s urgent care. The nurse checked me in and asked to see the Apple ECG report. She said she could see the AFib. I saw the doctor and they confirmed AFib. I was referred to a cardiologist and put on Warfrin. A few months later I developed a flutter which made me feel exhausted while exercising. I saw an electro cardiologist and he did an ablation. I am now able to exercise regularly and my heart seems to be functioning correctly. The Apple Watch tipped me off to a heart problem. I am hoping for future technology advancements to help me live a more healthy life. I am 64 years old.
Eight weeks ago I completed a stenuous workout on my traithlon bike prior to the Ironman race in St. George. My Apple watch alerted me with an alarm that my heart rate jumped to 122 but the haptics noted I was sitting, I activated the ECG function and discovered I was in A fib. Five days ago I underwent an apparently successful cardiac ablation which may allow me to come off blood thinners eventually. I may have discovered this on my own but perhaps not and I would be a stroke victim like so many other folks with undedected A fib. Thanks for bringing this to everyone's attention.
My husband got me an Apple Watch because my heart was jumping frequently and we wanted to see if we could “catch” something on the watch.
Dec 2019, my heart felt as if it was skipping beats and going to beat out of my chest. I started the ECG feature on my Apple Watch. The reading said I was AFIB and my heart rate kept climbing. I went to the ER and showed them the reading. The ER confirmed I was in AFIB with my heart rate increasing. I was cardioverted and eventually had a follow up with Cardiology. I also catch PVCs on my watch.
It’s amazing that smart watches have these features.
WOW !!! The best explanation of heart function and ECG interpretation I've ever seen. Kept simple. Thank you, as a emergency medical responder in my younger days, I've always loved this sort of instruction.
I am a retired nurse of 45 years. I could never get my head round ECGs but you have made it much more understandable. I have heart problems so I will take a look at these watches and hopefully be able to afford one. Thank you
Liked how you stopped at 6:00 and had to explain our body's natural pacemaker. Most target audience would be confused. Good on yah.
These watches are amazing. My Samsung watch actually alerted me to poor blood oxygen at night. I then bought an air quality reader, and I was breathing in some pretty nasty stuff. I then purchased several air purifiers, and my air quality improved, and so has my sleep readings on my Samsung watch showing me getting better oxygen and rem sleep.
Every med student should see this, it simply makes sense and is easy to recall.
The best explanation of AFIB I've seen. Wonderfully clear. Thank you, Dr. Seheult!
Dr. John Campbell + Medcram are the best 👍
My pastor got several notices of afib from his Apple Watch. ER doc said it saved his life.
The most lucid and detailed explanation of heart function I have found! I have afib and had an ablation to restore the sinus rhythm. Dr. Seheult's diagrammatic approach clearly delineates the electrical pathways and possible dysfunctions much more explicitly than any of the cardiologists or electrophysiologists that treated me. A really valuable video (and I personally appreciate the straightforward tutorial without lots of aren't-I-cute lame doctor jokes and irrelevant graphic cuts that permeate other videos I have watched). I will save and review.
My goodness. Where have you been all my unhealthy life?! Glad I finally found you.
This is SO WELL explained for us normal people that don’t understand the medial complex of the human heart. Thank you for taking the time to do this.
Thank you for a clear explanation of exactly what the Apple watch captures and what the first lead shows. I've been watching a number of videos (mostly yours) to try to understand what is happening in my AF. Last week I had a cardiac ablation and have been out of AF since the procedure. What a difference! After four months of persistent AF it was as if I had aged 30 years overnight (I am 63). My brain was like that of an old person, and I became weak and out of breath easily. My tech-savvy son gave me his watch and it confirmed when I felt I was in afib. It provided other useful information, and also encouraged me to remain active and to "breathe." These lectures are the BEST teaching I've ever experienced. You take such complicated processes and break them down so that even an English major can get the gist of what happens.
Hang in there… it takes a couple of months for the scars to form.. I’ve had 4 cardiac ablations and a dual chamber pacemaker and the pulmonary vein isolation ablation was by far the most complicated and the only one I was out for 3-4 hours. Other ablations I had improvements right away but this one takes a long time and patience.. I had severe episodes of a fib for several months and was given amiodarone to try to stop it. Some people need 2 of the procedures especially if persistent a fib but it’s usually very successful. A fib is NO fun and I’ve had every single arrhythmia and it was the worst of them all. I hope you continue to feel better and better!
My Apple Watch also helped me figure out I had a Pulmonary embolism.
It alerted me of an high resting heart rate. I thought it was due to taking a higher then normal insulin dose due to a high carb meal. but when I got working I nearly passed out.
And it alarmed again and I must have touched some thing this time I knew something wasn't right.
so I didn't hav any chest pains so I had my wife take me to the ER and after an Xray and a CT I was told I had Two very large Pulmonary embolisms one in each lung and my doctor told me if I didn't listen to the watch I would have passed away in my sleep that night.
That’s amazing. Thank you for sharing.
Very clear, precise , accurate , simple explanation how to interpret ECG waves particularly the first stage, big help and informative.
What a beautiful explanation of a somewhat complex phenomenon. It will definitely help me make sense of some of the applications of signal analysis in my Electrical Engineering classes.
As one with heart disease this information is so helpful. Thank you for removing the mystery from the ecg results of my Apple Watch!
Thank you for your great video! Fitbit Charge 5 now has this feature (the firmware was released). I just checked my ECG and everything is normal. Now I know what I am looking at, and why it is important.
I have had and been treated for both Afib and a fast running heart. Have had ablation done 4 times with the final result being unable to reach the issue on the left side. currently on medication which has been for the most part successful. I just wanted to pass on that this video has been the best explained i have ever seen. I wish i had seen this in the beginning to completely understand how it all works. Thank you so much for sharing this !
Thanks You Roger for another great video! :) and as always so well-explained that even a novice like me can understand these complex systems! I had Afib for almost 20 years, but finally (2015) got an dual ablation done, both cryo and electrical burn, which helped me alot! not 100% but much better!
Anyway, you helped me to finally understand what A-fib is. Thank You!
Thank you Dr. Seheult this was a great explanation! I wondered how that all worked. I work with electronics and I use an oscilloscope to diagnose circuits, I know what signals to expect, how to hunt them down, and what I need to do to fix them... However, today... you did a wonderful thing for me: You connected the dots for me how to relate the heart's electrical activity to essentially a trace on an oscilloscope... if, as you say, it is open to non-medical people (that's me)... I thought I had to be a Doctor or Nurse in the medical field to take courses... Wow! That opens a door for me! I'm curious and want to learn, I'll check into that course and depending what I've got going on... I might even take it!
Knowledge is power. If there's one thing that we should be knowledgeable about it is our own health! I am glad this was an A HA moment for you!
@@rogerseheult1312 Yes it truly was an "A HA!! moment" With a heart-felt, pun intended, Thank you so very very much... Agreed: Education is the key to understanding our health, and it is through teachers like you, with excellent communications skills, that make it possible! I look forward to learning more from your channel. Cheers and wishing you happy holidays Dr. Seheult (BTW: any more music videos possible?)
Thank you Dr Seheult. It's always good to have a bit of a change of pace from the COVID videos and all the comments associated with them.
You have a true gift for teaching. Great information in a very easy to understand lecture but still very in depth. Much appreciated!
Thanks so much for your explanation of ECG’s, that was great!
I was really glad I have my Apple Watch….I have had odd feelings of a increased heart rate for YEARS, but all my ECG’s were fine, even had a nuclear stress test (prior to a surgery I needed).
The watch managed to catch my HR in the 200’s when I was working. I work in a hospital, so when it wouldn’t go back to a normal rate, I went to the ER to get it checked. Here I had SVT,
had it for years, probably, but I’d always go back to a normal HR. It wasn’t going back this time, and needed meds to go back to a normal HR.
Thanks to the watch, I was able to finally get treatment *got an ablation*😊
I'm almost 44, and I bought the Samsung watch 3 weeks ago. I highly recommend. I can see my Heart Rate and ECG. I've had shortness of breath and etc. I see a cardiologist now as of January. I had an Echo and stress test. I pass the stress tests, echos and etc. Some regurgitation in my echo that I'm told a lot of people have. But the watch does give me a lot of peace of mind. I do have a diagnosis of severe anxiety.
Probably the best explanation of heart function I have ever seen (and I've seen plenty). Thanks so much.
Best explanation ever !
Over the top/ excellent presentation & description !
The drawings, accompanied by the articulate reader , at an easy to understand pace is awesome !
Thank you for "filling in" my too many voids of what the process was all about !!!
Best explanation I've heard about the basics of the electrical conduction system of the heart and simple ECG reading. 👏
The best (non-pro) explanation I've seen on this subject. Thank you! 🙏
This is absolutely the best explanation of heart activity I have ever seen; in just a few minutes I "get it". Thank you!!!
To Dr. Schuelt, I sincerely appreciate all you do in service to your fellow human.
That is most useful. I now understand the issue a lot more than before. What makes it slightly confusing for me is that I have an irregular heartbeat - or as my practice nurse described it "a regular irregular heartbeat". I can now see how to view this WITH the other parts of the wave. Thank you.
Complex made easy. A gift few have!
Excellent video! Thank you! The best by far I've seen on explaining ECGs.
Can't Thank You enough for the awesome knowledge that I've learned/learning from your channel.
Hey Doc, this presentation was uniformly superb. You have so much to be proud of. A clear, concise, explanation of Atrial Fibrillation supported by an easy to comprehend diagrammatic heart pathway sketch.In addition, you have a clear , D.J. type voice, of smooth enunciation. You are a gifted communicator besides being an M.D. with an amazing skillset.
May I ask what state you are in & do you have a practice? Always be safe & thanks,phil🇺🇲🍀💙🙏👍
What an awesome video. I came to get a basic understanding of how to read ecg results from my watch and left with a better understanding of how the heart works. What a miracle machine.
Thank you very much. I finally get a small understanding of what those ECG diagrams mean.
Thank you for all your amazing videos and explanations, Dr. Seheult! Could you also please make a video on wearable (cuff-less) blood pressure monitoring technology and how accurate it is?
Thank you for making this fun and easy to understand.
Thank you for this, I've had many ECGs in my day, thanks to my weird heart and poor hydration skills. when i get dehydrated (went to ERs before I figured out on my own the common factor but I digress) they once called it pre-ventricular fib, where my hear beat would be super short between P and R but all my R's were in perfect time. turns out when I don't drink enough water my heart has a tendency to short out that delay circuit and I can feel it when it's happening which then triggers a panic attack and sets off that spiral I'm sure I don't need to explain here, I never really understood what I was looking at when I saw the charts other than how synchronous those R waves were. Thank you for the detailed explanation. I hope it is many years before I look at another one but at least now I will understand more of what I am looking at.
Great video, not bamboozled with terminology, great teaching style.
Thank you! I needed this to understand my heart better! I remember learning the structure and function of the heart in high school Biology class, loved it, but didn't remember any of it until this excellent illustrative video. I have developed A-Fib and I didn't know how to relate the function of my heart to the EKG printout. I underwent Cardioversion 4 hours into A-Fib, it worked perfectly, and like you said, my cardiologist had a serious discussion with me about using blood thinners or not. We chose not to as it was only 4 hours and I have no other health issues. I ate quite a lot of raw garlic for the following week as my own blood thinner. Dr. couldn't say that was good or bad, but probably wouldn't hurt. I may or may not get one of these watches as my heart thumps and bumps weirdly many times a day, fribulates for a couple of second at a time pretty much daily, and has since I was about 17. I can really feel it. Its very obvious. Thank you - I love knowing exactly what's going on with my dear heart. Love your videos!! ❤
I am just glad Samsung finally added both fall detection due to heart failure as well as a heart stopage alert for you like Apple has had for a while now. I sleep with mine on, not dead yet.
Without a doubt one of the best explanations of normal cardiac rhythm and A Fib that I have ever seen! Thanks Doc for all of your excellent videos. Hope that you & your family are doing well and staying safe! BTW, I got my Moderna COVID booster vaccine yesterday. Hope that everyone does the same! 👍😉
Thank you for detailed and organized explanation. I have learned so much from this. Despite not being from the medical background, I look forward to checking out more videos from your channel. Please keep up the amazing work.
Thank you, that is amazing and you explained it in a way I could understand it.
This gentleman is a very good teacher/speaker.👍🏼
Very cool! It's nice to understand what the data means. When I had a lot of work stress, I was getting sharp pain in my chest so I checked the ECG on my apple watch. It showed that the pain in my chest happened during an off-rhythm spike, which I'm now guessing is the QRS area.
Excellent discussion--clear, concise information. Thank you.
Thank you for your straightforward and thoughtful video. Very much appreciated.
Thanks for the easy to understand explanation (with visual) of heart and AFIB. I finally have a general idea of how heart works!! (despite trying before with other books and narrations) Kudos
Thanks, will be upgrading my smart watch next year, to one that can do ECG.
Best presentation ever for an ECG
Thank you for such a clear way of putting it together and made easy to understand
You have made it very simple to understand the ecg... thank you soo much...I watched many videos tried to get understanding about p wave and qrs... But Was never able to get it....
Thank you for such a crystal clear explanation
Top stuff. Excellent explanation
Absolutely stunning!! Afib explained in simple english. Kudos to the doctor for doing this 🙂
This really x helped me understand not only my AFib but QT prolongation. I love being able to look at my Apple Watch ECG report and know what it’s showing.
Thank you so much I do appreciate your explanation of your diagram 😇🙏
I am glad that standard practices are regularly reviewed. In 2004 I landed in hospital with double Pneumonia. They started an IV and flushed the port with Heparin before hooking up a bag. Turns out that I was allergic to Heparin. It caused HIT which is known but rather rare.
I was pleased to learn that flushing new IVs with a blast of Heparin has been replaced by flushing new IV ports with saline solution instead!
Thank you for making these
Thank you for this wonderful explanation!!
Very clear to this retired nurse…at last it’s sunk in! Thanks 😊
Wow. A very clear explanation! Need to stay focused for it the whole time.
A really well put together video. Clear and informative. Thanks for posting
Excellent video but it spurs several questions; a) what causes the sinus irregularity and can it be resolved without medical intervention, ie, thru diet, exercise, electrolyte adjustments, etc. b) how long must afib last and how severe must it be to warrant concern and intervention
You are such a wonderful teacher! Explanation is super clear and concise! Thanks so much! I am sure you saved many people from potential troubles and all of them are grateful to you! Me too!
Thank you so much for detailed information.
very helpful topic. simple and clear. thanks doc!.
What a great explanation! Thank you!
very detail and good education for us. Tks Dr
I have cardiomyopathy and have a pacemaker and Apple Watch ….Thanks for this very good explanation !
Thank you doctor for your wonderful information. Many stories we have heard that those who wears this watch saved their lives. Non medical professionals like us also can easily understood. Great!!!
Thanks for the explanations. Very interesting.
I loved this video doctor. the explanations were detailed and thorough. I gave me some thought on how to manage my own heart abberations...if and when they may appear ...and if i have a smart watch that detects them I could seek medical advice immediately when any anomaly is reported.
I know the smart watch feature is a crude hit-or-miss tool at best, but at least I have that available....
Thank you doctor.
Fantastic explanation for non medical person(Me). Thank you for these fantastic videos
Such a great explanation! Thanks!
Great video. Never taught could learn this such heart complex in simple form
What an outstanding video. Very useful info for using my Samsung Smart Watch 4! Thank you so much!
Clearly explained by an expert. Thank you good sir.
Outstanding presentation!, thank you, Doctor
Thank you very much Doctor for excellent explanation 🪻
Thank you ! You videos are very clear and very helpful !
I bought a model 4 Apple Watch 4 years ago. I found several skipped beats. Heart rates as low as 32 bpm. It was diagnosed as PCVs and had two ablation procedures about 18 months apart. That second ablation fixed my issue and life is much better since then.
this is really good information presented very, very well. l also like that you stated and hope people paid attention that this is only an indicator as I will call it and not a full heart monitor setup but to go get checked by own medical professional.
very good video.
simply amazing the way the heart works. very good explination
Excellent presentation. Thank you.
Thank you very much for doing this. I have afib and I suffered a minor stroke a few years ago. I recovered and was placed on Xarelto. As time went by, the afib became persistent. I have seen an epiphysiologist and I am now on an anti arhythmatic med and scheduled for electro cardioversion shortly. Is it beneficial for a patient such as me to have such a device during the medicinal treatment, after electro conversion and if and when I undergo an ablation?
Very helpful. Clarifies what an apple watch is actually assessing. The real time potential difference between left and right arms.
Thanks Doc fir your explanation, very informative.
Wow!!! This was a great vid.... thanks a lot Doc for a great explanation on the topic.....👍🙏
Thanks for this explanation.
Was just searching for the ECG feature on a watch, but the explanation was so good, I ended up being able to read a lead 1 only ECG. Hahaha
Interesting video... and timing. I have atrial fibrillation since i had covid in april. I have been checked out, and diagnosed. Sometimes daily, sometimes just every 6-10 days fibrillating. I am waiting for a catheter ablation ever since, no date yet (hungarian healthcare at its finest). But they also didnt put me on anticoagulants. They say i am 40, and have no other risks. Of course i am starting to doubth all these, after all the time passed without intervention... I wonder if i should push for anti coagulants? Or just keep pushing for an ablation date....
Very well explained. Thank you.
