The SA node (SA stands for sinoatrial) is one of the major elements in the cardiac conduction system, the system that controls the heart rate. Location: The SA node consists of a cluster of cells that are situated in the upper part of the wall of the right atrium (the right upper chamber of the heart).
SA nodes stand for "Sinoatrial nodes." These are small clusters of cells located in the right atrium of the heart. They are often referred to as the heart's natural pacemaker. The SA node generates electrical impulses that regulate the heart's rhythm by initiating each heartbeat and coordinating the contractions between the atria and the ventricles.
