What a no nonsense approach! Loved that it had no music. This channel is a gem. Great way to teach.

Amazing. So many concepts cleared in just 11 minutes. This type of teaching must be adopted everywhere👏

Thank you! I recently got diagnosed with 1st degree heart block, and this really explained it in a depth that google couldn't!

[frankfleming]

That video was AMAZING!!! GREAT BREAKDOWN! The patient cases really help bring it home!

[BakaSama]

Love how there was also a patient case to apply this knowledge

Right on time for my cardiology shadowing

Thank you for the well-made video. The only confusion I have is how Mobitz 1 can cause increasing P-R intervals. What exactly is going on in the AV node for there to be slower and slower conduction to the ventricles?

What an absolutely video with such beautiful

I really love this video! I do have a doubt on the 7:05 minute, the configuration showed is in fact a rR'configuration, as the S wave doesnt pass the baseline. Also, when trying to identify the waves, both R waves are negative deflections and the S wave is a positive deflection, which goes against the definition of both R and S waves. Which one is correct then? Is it a rR' configuration or is it a rSR' configuration? Thank you!

I went to the doctors to get cleared for a non invasive spinal surgery. My restring BPM is around 40-50. Closer to 40 when I'm really still and calm. I constantly workout and focus on pretty intense endurance training and have also been in and out of martial arts most of my life. I also ride BMX agressively back and forth to work almost everyday. I have relatively normal blood preasure. My systolic sometimes runs high if I feel anxiety in situations like TAKING MEDICAL TESTS. When I'm home and I test myself my blood preasure is always normal. After taking an ECG/ekg (i forget which) I was told they suspect an AV block. I never have had any symptoms infact I feel great with lots of energy. No dizzyness, no passing out, no nausea, no nothing.

Is it not more likely I have an athletes heart and that my heart has made adaptations and that the walls of my ventricals are just thicker than the average person? Thank you.
