I'm having my exam this morning... thank you for making it clear in injury time 👏😊

AV node pacemaker cells have more K+ permeability during the prepotential phase (Phase 4); The increased K+ efflux causes a greater counterbalance against Na+ influx, therefore the prepotential phase is prolonged.
With more prolonged prepotential phases, the network of cells inside the AV node take longer to transmit the action potential to one another.
That is why the AV node slows conduction.

Thank you for the explanation! Very helpful for the MCAT students

[@Sarakasarah]

after surfing entire youtube, your videos popped. thankyou for explaining so beautifully and in very less time. it would be great if you start guyton series or try to teach all guyton points in this well🥹🥹

[@zdeyji]

great explanation thank you !!

Thank you 🫶

[@thecutelittlesquirrel]

Can you please make GASTROINTESTINAL SYSTEM PHYSIOLOGY videos as soon as possible??
Please.....

[@nzar75]

i dont know why teacher or doctors dont show these videos for their students or med students
