Cardiac Resynchronization Therapy Response Is Equalized in Men and Women by Electrical Optimization

This study hypothesized that the shorter intrinsic PR interval observed in women allows a greater degree of fusion with intrinsic conduction, achieving a shorter QRS interval duration and, thus, a better response.Women benefit more from cardiac resynchronization therapy (CRT) than men. However, the reason for this difference remains elusive.A cohort of 180 patients included in the BEST (Fusion based optimization in resynchronization therapy [ECG...
