Biological pacemaker - Wikipedia

WebPacemaker cells differ from cardiac myocytes in that they are specialized cells that are responsible for setting the heart rate. Pacemaker cells are found in the sinoatrial (SA) node, located in the right atrium, the atrioventricular (AV) node, located in the interatrial septum, and the bundle of His, located between the right and left ventricles. WebPrimary pacemaker. The sinoatrial node (SA node) is the primary pacemaker of the heart. It is a region of cardiac muscle on the wall of the upper right atrium near to the superior vena cava entrance. The cells that make up the SA node are specialized cardiomyocytes known as pacemaker cells that can spontaneously generate cardiac action potentials.These … hawks vs pistons highlights
