Patients with PAF who were refractory to or intolerant of antiarrhythmic drug therapy received a Medtronic Thera DR pacemaker 3 months prior to a planned total AV node ablation. Patients were randomized to atrial pacing or no pacing therapy. The time to first recurrence of sustained PAF was the primary study outcome event. Following AV node ablation, patients were randomized to the DDDR or VDD mode in a crossover study design. Patients were followed in each mode for 6 months. The time course of PAF recurrence was compared for each pacing mode.<\/jats:p>","DOI":"10.1053\/eupc.1998.0005","type":"journal-article","created":{"date-parts":[[2003,7,22]],"date-time":"2003-07-22T20:16:03Z","timestamp":1058904963000},"page":"40-42","source":"Crossref","is-referenced-by-count":5,"title":["The Atrial Pacing Peri-ablation for Paroxysmal Atrial Fibrillation (PA3) Study"],"prefix":"10.1093","volume":"1","author":[{"given":"A.
