A 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 main components of the cardiac conduction system are the SA node, AV node, the bundle of His, bundle branches, and Purkinje fibers. The cardiac conduction system is a collection of nodes and specialised conduction cells that initiate and co-ordinate contraction of the heart muscle. It consists of: Sinoatrial node Atrioventricular node Atrioventricular bundle (bundle of His) Purkinje fibres long strands of barrel shaped cells with few myofibrils complete the pathway through the interventricular septum , penetrate into the heart apex and then turn superiorly into the ventricular walls. the bundle branches excite the septal cells, but the bulk of ventricular depolarization depends on the large purkinje fibers and ultimately on cell to cell transmission of the impulse via gap junctions between the ventricular muscle cells. because the left ventricle is much larger than the right ...

The heart's electrical system. In the simplest terms, the heart is a pump made up of muscle tissue. Like all muscle, the heart needs a source of energy and oxygen to function. The heart's pumping action is regulated by an electrical conduction system that coordinates the contraction of the various chambers of the heart. How does the heart beat?
