ANATOMY

Detailed explanation-1: -To do this, it relies on a specialized network of cells called the cardiac conduction system . It’s also known as your heart’s electrical system. Cells in the cardiac conduction system can generate electrical impulses and then distribute the signal throughout your heart.

Detailed explanation-2: -The atrioventricular node (AVN) is a complex structure that performs a variety of functions in the heart. The AVN is primarily an electrical gatekeeper between the atria and ventricles and introduces a delay between atrial and ventricular excitation, allowing for efficient ventricular filling.

Detailed explanation-3: -After passing through the AV node, the electrical current then continues down the conduction pathway, through a pathway called the bundle of His, and into the ventricles. The bundle of His divides into right and left pathways (bundle branches) to give electrical stimulation to the right and left ventricles.

Detailed explanation-4: -The bundle of His is also called the atrioventricular bundle. It is a branch of fibers (nerve cells) that extends from your AV node. This fiber bundle receives the electrical signal from the AV node and carries it to the Purkinje fibers.
