The cardiac cycle and conduction system represents the mechanical events of one heartbeat at rest one complete cycle lasts 08 seconds and is repeated approximately 72 times per minute. Electrical conduction system of the heart (cardiac conduction system): this video explains how the sa node, av node, bundle of his, right and left bundle bra. Overview the cardiac conduction system is a group of specialized cardiac muscle cells in the walls of the heart that send signals to the heart muscle causing it to contract. The conduction of electrical impulses throughout the heart, and particularly in the specialized conduction system, is influenced by autonomic nerve activity.
Check out this image and learn more on medlineplus: conduction system of the heart. The conduction system of the heart consists of cells and fibers which serve as a pathway for the transmission of electrical impulses in the heart, resulting in heartbeats. The normal electrical conduction in the heart allows the impulse that is generated by the sinoatrial node(sa node), situated in the walls of right atrium of the heart to be propagated to and stimulate the muscle of the atria and ventricles(myocardium. The human heart beats 25 billion times during a normal lifespan, a feat accomplished by cells of the cardiac conduction system (ccs) the functional components of the ccs can be broadly divided into the impulse generating nodes and the impulse propagating his-purkinje system human.
