Abstract
This study evaluated the impact of the atrial lead implantation site on the subsequent development of atrial arrhythmias. Dual chamber pacemakers were implanted in 109 consecutive patients. The indication was AV-block in 51 patients, sick sinus syndrome in 58 patients. No patient had chronic atrial fibrillation, but 12 patients (11%) had paroxysmal atrial fibrillation before implantation. Patients were classified according to the atrial lead implantation site: right atrial appendage and right atrial free wall. Preimplant episodes of atrial fibrillation were similar in patients with lead implantation at the free wall and with implantation in the right atrial appendix (13% vs 7.5%, P=0.53). During a mean follow-up of 24+/-13 months, new paroxysmal atrial fibrillation occurred in 5% after lead implantation in the appendix vs 28% of patients after implantation at the right atrial free wall (P = 0.004). The development of atrial arrhythmias in dual chamber pacing is influenced by the implantation site of the atrial lead. The frequency of atrial arrhythmias during follow-up is higher after atrial lead implantation at the right lateral wall than in the appendix.
