MVP Promotes Intrinsic Conduction

A patient's risk of AF doubles with ventricular pacing (DDD-L or DDD-S) vs. atrial pacing (AAIR).1 Even with long AV delays, programmed DDD pacing leads to AF.1

In patients with sinus node dysfunction:

  • When ventricular pacing is less than 40%, for each 10% increase in ventricular pacing there is a 54% relative increase in risk for heart failure hospitalization.2
  • When ventricular pacing is greater than 40%, a patient's relative risk for heart failure hospitalization remains constant.2
  • The risk of atrial fibrillation increases linearly as the percentage of ventricular pacing increases from 0% to 85%.2

Promoting Intrinsic Conduction Without Compromising Safety

Managed Ventricular Pacing (MVP®) is an atrial-based pacing mode that significantly reduces unnecessary right ventricular pacing 2,3 by primarily operating in an AAI(R) pacing mode while providing the safety of a dual chamber backup mode if necessary.
