Overview
Mounting evidence suggests that right ventricular pacing is associated with a variety of detrimental effects. Most notably, unnecessary right ventricular pacing can lead to an increase of 8% risk of heart failure death per 10% increase in right ventricular pacing.1 Furthermore, right ventricular pacing is associated with a 1% increase in risk of AF for each 1% increase in cumulative right ventricular pacing.2
Managed Ventricular Pacing (MVP™) reduces unnecessary right ventricular pacing by 99%.3
RISK OF AF2
Reducing unnecessary ventricular pacing has been shown to improve clinical outcomes by reducing the risks of atrial fibrillation (AF)2, 4-6 and heart failure hospitalisation (HFH).2,4
How does MVP work?
The Managed Ventricular Pacing (MVP) modes promote intrinsic conduction by reducing unnecessary right ventricular pacing. These modes provide atrial-based pacing with ventricular backup. If AV conduction is lost, the device is designed to switch to DDDR or DDD mode. Periodic conduction checks are performed, and if AV conduction resumes, the device switches back to AAIR or AAI mode.
