Definitions:

AV Node Depolarization

The process wherein the atrioventricular node undergoes a change in charge distribution, leading to the transmission of electrical impulses from the atria to the ventricles in the heart.

Ventricular Filling

The phase of the cardiac cycle in which the heart's ventricles fill with blood coming from the atria.

Atrial Contraction

The phase of the cardiac cycle in which the atria of the heart contract to pump blood into the ventricles.

QRS Complex

A series of three deflections in an electrocardiogram (ECG) representing the depolarization of the heart's ventricles before contraction.
