Managed Ventricular Pacing (MVP)
Managed Ventricular Pacing (MVP™) is a dual-chamber pacemaker mode invented by Medtronic engineers, Casavant, Belk, Mullens and Stroebel. At the time of commercial release in 2004, MVP was considered revolutionary as it “unlocked” conventional dual-chamber pacing by not consistently requiring a 1:1 atrioventricular relationship defined by an AV delay during its predominant operating mode (i.e. AAI/R+). Importantly, the mode continuously protected against transient heart block by switching to DDD/R mode in the instance of dropped ventricular beats. Restoration of AAI/R+ following DDD/R reversion occured by withholding singular ventricular paced events at geometrically increasing intervals (i.e. 1 minute, 2 minute, 4 minutes, 8 minutes,up to 16 hours).

In 2020, Medtronic's MVP modality continues to be a widely prescribed pacing therapy in both dual-chamber pacemakers and ICDs.
