Complex catheter ablative procedures are being developed, but efficacy and safety issues remain to be clarified. We hypothesized that combined pharmacologic and simple ablative therapies in a targeted subset of patients will improve success in the treatment of atrial fibrillation.<\/jats:p><jats:p><jats:bold>Methods and Results: <\/jats:bold> We identified 13 patients (mean age 61.5 \u00b1 16.2 years) with atrial fibrillation who converted to electrocardiographic atrial flutter during antiarrhythmic drug treatment. Surface ECG suggested \u201ctypical\u201d atrial flutter in 11 patients and \u201catypical\u201d atrial flutter in 2. Intracardiac mapping and entrainment studies revealed 9 patients had counter\u2010clockwise isthmus\u2010dependent atrial flutter, and the remaining 4 had complex activation patterns, suggesting the presence of multiple wavefronts. All 9 patients with typical atrial flutter underwent successful ablation. None of the 4 patients with complex activation patterns had successful ablation. Patients were followed for recurrences of atrial arrhythmias via clinic visits, record review, and interviews. In patients who underwent successful ablation and continued on antiarrhythmic drugs, 88.9% remain in sinus rhythm after a mean follow\u2010up of 14.3 \u00b1 6.9 months (range 1 to 28).<\/jats:p><jats:p><jats:bold>Conclusion: <\/jats:bold> In patients who experience conversion of atrial fibrillation to atrial flutter during antiarrhythmic drug treatment, ablation and continuation of pharmacologic therapy is a safe and effective means of achieving and maintaining sinus
