<P> 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 right atrium and right ventricle . The AV node lies at the lower back section of the interatrial septum near the opening of the coronary sinus , which conducts the normal electrical impulse from the atria to the ventricles . The AV node is quite compact ( ~ 1 x 3 x 5 mm ) . </P>
