The bundle of cardiac muscle fibers that begins at the atrioventricular node and passes through the right atrioventricular fibrous ring to the membranous part of the interventricular septum. It conducts the electrical impulse that regulates the heartbeat from the right atrium to the ventricles. Also called atrioventricular bundle, His bundle.
The bundle of cardiac muscle fibers that passes from the atrioventricular node to the interventricular septum and then the ventricles. It conducts the electrical impulses that regulate the heartbeat from the right atrium to the left and right ventricles.
