WebMar 28, 2024 · The first component, the SA node, acts as the pacemaker of the heart, as it sets the rhythm for the remaining components of the cardiac conduction system. These structures are all connected by specialized conduction fibers, which enable fast transmission of electrical impulses. WebThe SA node is thought to be the heart's pacemaker. It is located near the bottom of the heart, behind the right side of the liver and below the diaphragm. The SA node generates a spontaneous pulse every time it contracts. This pulse causes atrial muscles to contract, forcing blood into the atria. WebThe cardiac conduction system that is known as the pacemaker is the SA node. 3.
