Right Ventricular Pacing Burden-Dependent Biventricular Remodeling in Patients With Preserved Left Ventricular Ejection Fraction: A Prospective Longitudinal Study.
PURPOSE To assess right ventricular (RV) systolic trajectories across right ventricular pacing (RVP) burdens and their relationship with left ventricular (LV) remodeling in patients with preserved baseline LV ejection fraction (LVEF). METHODS This prospective study included 200 patients undergoing dual-chamber pacema...
