Study Summary

Recent exploratory studies suggest that pacemaker patients with diastolic dysfunction (DD) or heart failure with preserved ejection fraction (HFpEF) may benefit from a higher backup heart rate (HR) setting than the factory setting of 60 beats per minute (bpm). In this prospective double-blinded randomized controlled study, pacemaker patients with DD or overt HFpEF and either 1) intrinsic ventricular conduction or 2) conduction system or biventricular pacing will be enrolled and randomized to either a personalized lower HR setting (myPACE group, based on a height-based HR algorithm) or to the standard 60bpm backup setting (control group) for 1 year.

Primary Outcome

Change in score from baseline (at enrollment) to 1 month and 12 months after enrollment.

Interventions

  • DEVICE Adjustment of lower rate limit
  • DEVICE Maintenance of lower rate limit
