Left Ventricular-Only Pacing in Heart Failure Patients with Normal Atrioventricular Conduction Improves Global Function and Left Ventricular Regional Mechanics Compared with Biventricular Pacing: An Adaptive Cardiac Resynchronization Therapy Sub-Study

Abstract

In heart failure patients with normal AV conduction, LV-only pacing timed with native RV activation may result in greater improvements in LV ejection fraction and myocardial strain compared with biventricular pacing due to better apical and septal function.
