if an action potential could not be received by the atrioventricular node, despite the propagation through sinoatrial node, what
Fofino [41]

You would predict this to occur as an opening of atrioventricular valves, atria contraction, and filling of ventricles with blood if an action potential could not be received by the atrioventricular node, despite the propagation through the sinoatrial node.

So, the correct options are B, C &E.

It enables a left atrium action potential, causing both atria to contract simultaneously before the ventricles do. The AV delay delays the contraction of the ventricles by slowing the rate at which the impulse reaches them. This is significant because it gives the atria enough time to finish contracting so that the greatest amount of blood may be discharged into the ventricles.

The right and left atria to have time to contract first (eject blood to the ventricles) before the ventricles contract, which is why the AV node delay is so crucial. The AV node is a modified myocardium.
