Dr. Eric Strong, I would like to ask permission to use your EKG tracing at 4:40 in a video I am working on. I have taken a screen shot of it and placed it in the presentation materials. However, it's easily deleted. If allowed, it the video will have attribution (written and verbal comment), and recommendation to your channel and specifically your EKG playlist. Thanks for your considerations. Mike B. MD. Candidate Class 2018
+Mike Birkhead That sounds totally fine. If you send me personal message or an email with your email address listed, I'd be happy to send you the original picture file (which would be better resolution than a screen shot).
That's what I say in the video, although I may not mention the eponym Mobitz because its unnecessarily redundant. (There is no competing classification system for AV block.)
Hi, quick question, how can we distinguish, 2:1 2nd degree AV block from 3rd degree AV block? Because your example of 2:1 AV block could be also be interpreted as atria and ventricles beating at their own rate, with atria beating faster! It is true that in 2:1 block, each QRS is preceded by a P wave, but this finding can even be seen in 3rd degree AV block (a random chance, where the adjacent atrial beats happen before the ventricular beat). Isn’t it?
I have been wondering this too, it is the thing İ never understood about Av blocks.İ know its late but did you ever find the answer? My hopes are high that you became a cardiologist or something in this past 7 years and will enlighten me with the answer
Can someone explain why 2nd Degree AV Block Type 2 distal to the AV node and His bundle creates a wide QRS complex, and a block within the His bundle creates a narrow QRS complex? I know that junctional escape pacemakers use the His-Purkinje system which causes rapid ventricular depolarization and thus a narrow QRS complex, whereas ventricular escape pacemakers do not originate at the His bundle and therefore cause slow ventricular depolarization and thus a wide QRS. This makes sense in 3rd Degree AV Block in which there is complete AV dissociation and latent pacemakers are forced to take over, but I do not understand why these principles apply in Mobitz Type 2. My understanding is that impulses from the SA node (rather than an escape pacemaker) are responsible for ventricular depolarization in Mobitz Type 2, but are intermittently non-conducted. So in my mind, shouldn't all conducted P-waves produce a narrow QRS complex?
I just wanted to say thank you for your time. This videos are extraordinary helpful
Thanks!
Thank You Dr Eric Strong.
These videos are awesome.
All ur ecg lessons are very helpful..
Thanks for the great job u r doing..
Big help for me.
Big thumbs up and like for your videos, Sir! I actually graduated from medschool and still learned something ;)))
Thank you so much .....you are a life saver in ecg interpretations
You sir are an absolute legend
Lovely, lovely stuff. Thank you very much
Thank you very much , deeply appreciated.
Thank you Doctor Strong.
Nice work......تم
Excellent presentation. Thank you.
Super ! Thank you very much Doctor Strong

Thank you sir your lectures are the best ever
Thanks dr eric great Job.👍👍
Thank you very much!
Thanks Dr Eric
Thank you so much doctor
thank you for another great video lecture....would you please do one on arrhythmia?
I think it's wrong description Mobitz type 1 has progressively increasing PR interval than missing qrs complex
That's what I say in the video, although I may not mention the eponym Mobitz because its unnecessarily redundant. (There is no competing classification system for AV block.)
Sir you are awesome👌

Hi Dr. Strong, thanks for the excellent lecture. I was wondering if you were planning to make a video on supraventricular tachycardias?
Yes. Supraventricular tachycardias will probably be out in 3-4 weeks.
Thank you!
thanks Dr
thanks dr ,really thank you very much
2nd degree type two is very similar to LBBB. I am confused
Thanks.
Thanks
Can you make Subtitle this video please!
