Supraventricular tachycardia (SVT) is an arrhythmia initiated above the ventricles, at or above the atrioventricular (AV) node. This cardiac rhythm occurs due to improper electrical conduction within the heart that disrupts the coordination of heartbeats.

SVT is a broad term for a number of tachyarrhythmias that originate above the ventricular electrical conduction system (Purkinje fibers).
