    Primary pacemaker cells located in the central region of the sinoatrial node (SA node) undergo spontaneous diastolic depolarization, which ultimately triggers the action potential (AP) upstroke. The excitatory AP wave front subsequently spreads through adjacent areas of the perinodal region to reach the crista terminalis and atrium. Repolarization of the pacemaker cells allows the cycle to repeat. This inherent cyclic behavior enables the SA node to serve as the normal pacemaker of the heart (7;
