|
Is responsible for the P wave on the ECG

|
Transmit the action potential from the AV node to the SA node
|
|
|
Is the ventricular electrical conduction system
|
|
|
Transmits the action potential from the ventricular myocardial cells to the AV node

Detailed explanation-1: -The distal portion, known as the ventricular conduction system, allows for the rapid transmission of impulses from the atrioventricular node to the ventricular myocardium and plays a central role in cardiac function as well as disease when perturbed.
Detailed explanation-2: -The His-Purkinje System (HPS) is responsible for the rapid electric conduction in the ventricles. It relays electrical impulses from the atrioventricular node to the muscle cells and, thus, coordinates the contraction of ventricles in order to ensure proper cardiac pump function.
Detailed explanation-3: -Purkinje fibers or Purkinje cardiomyocytes are part of the whole complex of the cardiac conduction system, which is today classified as specific heart muscle tissue responsible for the generation of the heart impulses.
