Cardiac Conduction. The heart is composed of three specialized cells. Pacemaker, Purkinje, and Contractile. Pacemaker cells have automaticity that undergo spontaneous electrical depolarization that initiates an electrical impulse. The Purkinje cells conduct electrical impulses more quickly than other cells, and the Contractile cells compose the majority of the heart and contract when the electrical depolarization reaches them..
