Automaticity and rhythmicity. Concept introduction: The myocardium of the heart helps to enable the transmission of electrical impulses (action potentials) for the continuous repetition of the cardiac cycle. It consists of its own pacemaker and conduction system (specialized cells), concentrated at two sites (SA and AV node), for the generation and transmission of electrical impulses. The conduction pathway of the heart starts when the electrical impulse travels from the sinus node and ends at the Purkinje fibers.
