thanks Dr

thank you for another great video lecture....would you please do one on arrhythmia?

Thanks.

Thanks!

Thanks

Hi Dr. Strong, thanks for the excellent lecture. I was wondering if you were planning to make a video on supraventricular tachycardias?

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?

2nd degree type two is very similar to LBBB. I am confused

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

Can you make Subtitle this video please!

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?
