Upgrading to resynchronization therapy after chronic right ventricular pacing improves left ventricular remodelling

摘要

Aims Chronic right ventricular (RV) pacing may impose ventricular dyssynchrony leading to LV remodelling and is associated with increased morbidity and mortality. Upgrading patients with chronic RV pacing to cardiac resynchronization therapy (CRT) may be considered to restore synchronicity and prevent these deleterious effects.
