Definitions:

Ventricles

The two lower chambers of the heart that receive blood from the atria above them and contract to push blood into the arteries.

Atrioventricular Bundle

The bundle of His, a collection of heart muscle cells specialized for electrical conduction that transmits the electrical impulses from the atria down to the ventricles.

Ventricular Depolarization

The electrical activation of the ventricles of the heart, leading to their contraction.

Atrioventricular Node

A small node of specialized heart muscle located in the heart's lower right atrium, playing a crucial role in the heart's electrical conduction system by delaying the transmission of impulses from the atria to the ventricles.
