Expert Answer
The action potential required for the rhythmic contractile activity of the heart is generated at the SA node. When the impulse is initiated, it results in the atrial systole.
AV node received the impulse from the SA node. When the impulse reaches at the AV node, the ventricular systole is initiated.
