WebbThe AV node is labelled 2. The atrioventricular node or AV node electrically connects the heart 's atria and ventricles to coordinate beating in the top of the heart; it is part of the electrical conduction system of the heart. [1] The AV node lies at the lower back section of the interatrial septum near the opening of the coronary sinus, and ... Webbventricular volume increases rapidly (period of rapid inflow) - this occurs because blood that accumulated in the atria during ventricular systole (when the AV valves were closed) now forces open the AV valves (because the pressure in the atria is now greater than the pressure in the ventricles). & flows quickly into the ventricles.
