What is the left AV node called? Overview of Sinoatrial and Atrioventricular Heart Nodes Heart Nodes - Sinoatrial and Atrioventricular Overview of the Atrioventricular Node (AV Node) Overview of the Atrioventricular Node (AV Node) The atrioventricular node or AV node is a part of the electrical conduction system of the heart that coordinates the top of the heart. It electrically connects the atria and ventricles. The AV node lies at the lower back section of the interatrial septum near the opening of the coronary sinus and conducts the normal electrical impulse from the atria to the ventricles. The AV node is quite compact (~1 x 3 x 5 mm). The atrioventricular node or AV node is a part of the electrical conduction system of the heart that coordinates the top of the heart.

The AV node is quite compact (~1 x 3 x 5 mm). It is located at the center of Koch's triangle —a triangle enclosed by the septal leaflet of the tricuspid valve the coronary sinus and the membranous part of the interatrial septum. Blood supply The blood supply of the AV node is from the atrioventricular nodal branch . The origin of this artery is most commonly (80-90% of hearts) a branch of the right coronary artery with the remainder originating from the left circumflex artery . This is associated with the dominance of the coronary artery circulation. In right-dominant individuals the blood supply is from the right coronary artery while in left dominant individuals it originates from the left circumflex artery.
