There is a time hold off inherent In this particular conduction approach setting up with the AV node and atria contraction and ending with ventricular contraction. This time hold off is essential because the atria should contract ahead of the ventricles.
The depolarization and repolarization with the heart are significant factors of your cardiac action possible. Devoid of these electrical adjustments, the heart would not manage to agreement and pump blood properly.
