APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -When the Purkinje fibers deliver electrical signals to your ventricles, the ventricles contract. As they contract, blood flows from your right ventricle to your pulmonary arteries and from your left ventricle to your aorta. The aorta is the body’s largest artery. It sends blood from your heart to the rest of your body.

Detailed explanation-2: -The Purkinje fibers connect with the ends of the bundle branches to form interweaving networks on the endocardial surface of both ventricles and transmit the cardiac impulse almost simultaneously to the entire right and left ventricular endocardium.

Detailed explanation-3: -Abstract. 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-4: -In the ventricles, action potentials travels along the interventricular septum to the apex of the heart, then spread up the endocardial surface of the walls of the ventricles. Purkinje fibers conduct action potentials to ventricular myocardial cells.
