It is the sinoatrial node of the intrinsic system of conduction that helps to stimulate the atrioventricular node. This helps to conduct impulses to the atrioventricular bundle. The short form of sinoatrial is SA. The SA node is the most important part of the heart and so is called the pacemaker of the heart. The SA is responsible for starting the electrical stimulation that spreads down to the heart.

The intrinsic conduction system controls the functioning of the heart. This is a group consisting of neural structures. This is located inside the heart and is responsible for causing the myocardium. The myocardium helps to contract and relax the muscles of the heart. This system is automatic and cannot be controlled.

The heart has a system known as the intrinsic conduction system. This system helps to determine the pace of the heartbeat. So the sinoatrial node is a part of this and helps to stimulate the AV node.
