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.

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)
