Atrial synchronous left ventricular only pacing with VDD pacemaker system - A cost effective alternative to conventional cardiac resynchronization therapy

摘要

Introduction: Atrial synchronous left ventricular (LV) only pacing using two leads and VDD pacemaker could be a cost effective alternative to conventional cardiac resynchronization therapy (CRT).Methods: We implanted right atrial (RA) and LV leads with VDD pulse generator (LV only pacing) in five carefully screened heart failure patients who could not afford conventional CRT. All had NYHA class III/IV symptoms despite maximal guideline directed medical therapy. The sensed atrioventricular delay was programmed to pre-excite the LV and achieve fusion beat Response to treatment was assessed at 6 months.
