Sinoatrial (SA) node fibers possess the ability to depolarize spontaneously until a threshold potential of about −40 mV is reached, which generates a new action potential (Fig. 2.3). These pacemaker action potentials spread to working myocardial fibers, resulting in working myocardium action potentials (Fig. 2.3).
