The atrioventricular (AV) node is a critical component of the heart's electrical conduction system. It is located on the right side of the atrial septum, near the tricuspid valve. The AV node serves as a gatekeeper, regulating the electrical impulses that pass from the atria to the ventricles. Understanding the AV node's function is essential for nurses, particularly those working in cardiology and critical care settings.
