Pacemaker can be life-saving in high grade atrioventricular (AV) blocks. But this reality is occasionally challenged by arrhythmias induced by ventricular pacing. Some of the events are related to automated pacemaker algorithms. Managed ventricular pacing (MVP) is one such example which has delivered benefits but has also been associated with ventricular tachyarrhythmias (VT). Our case is possibly the first report of hysteresis induced symptomatic VT.
