Single chamber pacemaker implantation leads to a desynchronization of ventricular depolarization. This study aims to evaluate the implant of biventricular versus univentricular pacemaker. 902 patients were included in the group with biventricular pacemaker and 908 in the univentricular pacing group. The primary objective was to evaluate the long-term mortality and needs hospitalization for heart failure. With a mean follow-up 5.6 years, 689 events (439 deaths and 250 hospitalizations) were observed. There were no differences in clinical events between the two groups as in the incidence of atrial fibrillation or falling ejection fraction.
