The structure in the heart known as the pacemaker is the sinoatrial (SA) node. The SA node is located in the right atrium, near the opening of the superior vena cava. It is responsible for initiating and regulating the electrical impulses that dictate the heart's rhythm, causing it to contract and pump blood effectively. The SA node's activity sets the pace for the heartbeat, which is why it is referred to as the natural pacemaker of the heart.
