Sa heart node
WebNormally, your SA node adjusts to your level of activity. For example, it increases the rate of impulses when you exercise and decreases the rate when you sleep. With the SA node conducting your heart’s rhythm, you are in “normal sinus rhythm.” This means your heart is beating at a regular rhythm and pace, about 60 to 100 times per minute. WebSA node is the first component of conducting a system of the heart. It is a small body of specialized muscular tissue in the wall of the right atrium of the heart, whereas AV node is the second component of conducting a system of the heart. It is a cluster of cells that controls the heart rate by receiving an electrical impulse from SA node.

WebThe SA (sinoatrial) node generates an electrical signal that causes the upper heart chambers (atria) to contract. The signal then passes through the AV (atrioventricular) … WebThe SA node (sinoatrial node) is the natural pacemaker of the heart. The impulse originates in the SA node, a tiny bundle of specialized cells found in the right atrium. The electrical activity spreads through the atria's walls, causing them to constrict. This causes blood to flow into the ventricles. The blood fills the ventricles and pushes ...
