Atrioventricular reciprocating tachycardia (AVRT) is a type of abnormal heart rhythm in which the electrical impulse that normally originates in the sinoatrial (SA) node of the heart is instead generated in an extra pathway. This extra pathway is usually an accessory pathway, which is an abnormal connection between the atria and ventricles of the heart. This extra pathway allows the electrical impulse to travel in both directions, resulting in a rapid, regular heartbeat. AVRT is usually caused by a congenital defect, but can also be caused by certain medications or other medical conditions. Treatment for AVRT usually involves medications or a procedure called ablation, which destroys the extra pathway.
