About this study

The goal of this clinical trial is to assess the clinical efficacy of physiological pacing combined with atrioventricular node ablation, in patients with Heart Failure with preserved Ejection Fraction (HFpEF) and well controlled permanent atrial fibrillation.The main question it aims to answer is that heart rate regularization added to physiological pacing - preventing the deleterious effect of right ventricular apical pacing - would reduce mortality and heart failure hospitalizations. Researchers will compare physiological pacing combined with atrioventricular node ablation (intervention arm) versus optimal pharmacological therapy (control arm) to see if physiological pacing combined with atrioventricular node ablation reduce time to the composite of all-cause mortality or hospitalization due to heart failure or intravenous diuretics (time frame 24 months). Participants will : * Be randomized in intervention arm or control arm. * Visit the clinic 3 months, 12 months and 24 months after the randomization for checkups and tests.
