Located in the superior right atrium, it automatically produces cyclical electrical activity to initiate each heartbeat in normal sinus rhythm. SAN dysfunction (SND) in humans, also known as ‘sick sinus syndrome’, can manifest as pathological bradycardia and asystolic pauses.

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). olmr law officeWebbSterile towels and a sheet will be placed around this area.
