Definitions:

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.

Left Bundle Branch

A pathway of heart muscle fibers responsible for conducting electrical impulses to the left side of the heart's ventricles.
