Key result
Inactivating the VIP TM algorithm and increasing the PVARP from 275 ms to 350 ms prevented further episodes of pacemaker-mediated tachycardia and ventricular tachycardia over 15 months.
Case Report (n=1)
Highlights the potential for pacemaker algorithms like VIP to initiate pacemaker-mediated tachycardia that can degenerate into ventricular tachycardia, which is correctable with reprogramming.

Reprogramming may avert PMT degenerating to VT; hypothesis-generating for VIP algorithm safety in device programming.
Calton et al. (2021) conducted a case report in Pacemaker-mediated tachycardia leading to ventricular tachycardia and syncope (n=1). Inactivation of VIP TM algorithm and increasing PVARP was evaluated on Episodes of PMT or VT. Inactivating the VIP TM algorithm and increasing the PVARP from 275 ms to 350 ms prevented further episodes of pacemaker-mediated tachycardia and ventricular tachycardia over 15 months.
