Heart Conduction Disorders

WebbThe components of the cardiac electrical conduction system are: 1) the SN, 2) the AV node, and 3) the His–Purkinje system. The role of this system is to generate and propagate the electrical impulse through the myocardium to produce each heartbeat. The SN serves as the cardiac pacemaker, which is located in the upper wall of the right atria (RA).
