ABSTRACT

Results of recent trials suggest that in patients with left ventricular dysfunction, interventricular synchrony is possibly more important than atrioventricular synchrony. In patients with AV block and conduction system disease, alternatives to right ventricular apical pacing are therefore needed

Keywords: pacing; physiologic pacing; dual chamber pacing; interventricular synchrony; atrioventricular synchrony

Abbreviations: AV, atrioventricular; COMPANION, comparison of medical therapy, pacing and defibrillation in heart failure; DAVID, dual-chamber pacing or ventricular backup pacing in patients with an implantable defibrillator; MOST, mode selection trial
