"WebParoxysmal Supraventricular Tachycardia. Paroxysmal supraventricular tachycardia (PSVT) is a tachydysrhythmia (average heart rate, 160–220 bpm) initiated and sustained by tissue at or above the AV node. Unlike sinus tachycardia, PSVT usually begins and ends abruptly. The incidence of PSVT in the US population is 2.25 per 1000 persons. " - Hdm vagal electrophysiology
