| Popis: | Aims To evaluate the efficacy of atrial pacing in the suppression of early reinitiation of atrial fibrillation after successful internal cardioversion. Methods and Results The efficacy of atrial pacing in suppressing early reinitiation of atrial fibrillation was studied in 12 of 45 (29%) patients with early reinitiation of atrial fibrillation after successful cardioversion. These patients were randomized to undergo either repeated defibrillation alone or repeated defibrillation followed by high right atrial pacing at 500ms in a crossover fashion. In patients with persistent early reinitiation of atrial fibrillation despite atrial pacing at 500ms and repeated defibrillation, atrial pacing at 300ms was tested. Lastly, if early reinitiation of atrial fibrillation persisted, administration of intravenous sotalol (1·5mg.kg−1) was tested. Atrial pacing at 500ms after defibrillation prevented early reinitiation of atrial fibrillation in five of 12 (42%) patients, and was significantly more effective than repeated defibrillation (0/9 patients, 0%, P |
