In a previous study by the same authors, 225 patients with sick-sinus syndrome were randomized to either single-chamber atrial or single-chamber ventricular pacing and followed for 3.3 years. The beneficial effect of atrial pacing found in the previous study was enhanced substantially in the current study. After long-term follow-up of up to 8 years, atrial pacing was associated with a significantly higher survival, less atrial fibrillation, fewer thromboembolic complications, less heart failure, and a low risk of AV block.
