Right ventricular pacing is an independent predictor for ventricular tachycardia/ventricular fibrillation occurrence and heart failure events in patients with an implantable cardioverter–defibrillator

摘要

Aims There is increasing evidence that right ventricular (RV) pacing may have detrimental effects by increasing morbidity and mortality for heart failure in implantable cardioverter–defibrillator (ICD) patients. In this study we prospectively tested the hypothesis that cumulative RV pacing increases ventricular tachycardia/ventricular fibrillation (VT/VF) occurrence (primary endpoint) and hospitalization and mortality for heart failure (secondary endpoint) in a predominantly secondary prophylactic ICD patient population.
