Overview of the Atrioventricular Node (AV Node)

Atrioventricular reentrant tachycardia (AVRT) is a type of supraventricular tachycardia (SVT). It accounts for about of all SVTs.

ATRIOVENTRICULAR NODE (AV NODE) - part of the electrical control system of the heart that coordinates the top of the heart. It electrically connects atrial and ventricular chambers. AV node is an area of specialized tissue between atria & ventricles of the heart, specifically in the posteroinferior region of the interatrial septum near the opening of the coronary sinus, which conducts the normal electrical impulse from the atria to the ventricles | Wikipedia

During normal sinus rhythm (NSR), the cardiac impulse originates in the sinus node in the atria and spreads through the atrioventricular node to the bundle branches in the ventricles (left). During atrial fibrillation, millions of wandering wavelets randomly migrate through the atria, producing an irregular heartbeat (right). (Infographic c/o Capital Cardiology)
