The heart's natural pacemaker is the
WebThe natural pacemaker of the heart is the sinoatrial node (SA node). The impulse starts in the SA node. The sinus node consists of a cluster of cells that are situated in the upper part of the wall of the right atrium. The electrical action propagates through the atria’s walls, causing its contraction. This propels the blood into ventricles.

WebA human heart has a natural pacemaker in the heart. This structure is called SA node or sinoatrial node. This site initiates heartbeat at a rate of 60 – 100 beats per minute. Under normal circumstances, in a healthy heart with normally functioning SA node, the beats are evenly spaced out. This evenly spaced out pattern of heartbeats is called ... WebThis pacemaker, also known as a cardiac resynchronization therapy (CRT) device, has three leads connected to the right atrium and both ventricles. We use the biventricular pacemaker to treat people with arrhythmias caused by advanced heart failure. For many people with heart failure, the left and right ventricles do not pump at the same time.
