Abstract

Symptomatic patients with sick sinus syndrome (SSS) are candidates for permanent pacemaker implantation. Single-chamber atrial (AAI) or dual-chamber (DDD) pacing rather than single-chamber ventricular (VVI) pacing is the recommended pacing mode, with rate response (-R) if appropriate [1]. Most retrospective studies have demonstrated that mortality is greater in VVI paced patients and that atrial-based pacing is hemodynamically superior and associated with a lower rate of atrial fibrillation (AF) and thromboembolic complications [2–6]. Other observational studies comparing physiological (AAI or DDD) with VVI pacing, while they confirmed that VVI pacing was an independent predictor of AF and stroke, did not identify any difference in mortality and heart failure incidence between the two groups [7–9].
