Right ventricular septal pacing as alternative for failed left ventricular lead implantation in cardiac resynchronization therapy candidates

Abstract

Right ventricular septal pacing from mid septum or RVOT pacing improves LVEF and LV synchrony in CRT candidates. Further improvement in LVEF was achieved by CRT, which remains the 'gold standard' therapy in these patients. However, RV septal pacing is worthy of further study as an alternative strategy when LV lead implantation fails.
