The PEP-HFpEF study is a prospective, single-center mechanistic study evaluating personalized heart rate pacing (myPACE) in patients with heart failure with preserved ejection fraction (HFpEF) and existing cardiac physiologic pacemakers. Participants will undergo sequential periods of standard and personalized pacing with serial physiologic assessments to evaluate the effects of myPACE on exercise capacity, cardiac function, biomarkers, quality of life, and clinical outcomes.
