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.

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.

But Again, thanks a lot ❤🙏

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

I've went through all these symptoms I've seen readouts that look very simular to my readouts. Especially ventricular Afib.

[@user-up8jx3mt6j]

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.

best video ever!

[@RhesusMedicine]

Glad it helped you!

[@TravelFreeBird]

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?

[@SIMRANDAGAR-lu9eu]

[@4BIDDEN.SECRETS]

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

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

There's a mistake at 4:58. PVCs may be dangerous if they exceed 10-15% of total heartbeats, not 10-15 per hour

[@andrew1234856]

Does the percentage change? U can change per hour to per minute and vice-versa?

[@RhesusMedicine]

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
