Key result
In patients who developed persistent atrial flutter during antiarrhythmic treatment for atrial fibrillation, radiofrequency ablation and continued pharmacologic therapy maintained sinus rhythm in 93%.

Does radiofrequency ablation combined with continued antiarrhythmic therapy maintain sinus rhythm in patients who develop persistent atrial flutter while treated for atrial fibrillation?

Does radiofrequency ablation combined with continued antiarrhythmic therapy maintain sinus rhythm in patients who develop persistent atrial flutter while treated for atrial fibrillation?
Radiofrequency ablation of the cavotricuspid isthmus allows safe and effective maintenance of sinus rhythm in patients who develop typical atrial flutter while on antiarrhythmic drugs for atrial fibrillation.
TAI et al. (1999) conducted a cohort in Atrial fibrillation (n=136). Amiodarone or propafenone therapy and subsequent radiofrequency ablation was evaluated on Maintenance of sinus rhythm after successful ablation. In patients who developed persistent atrial flutter during antiarrhythmic treatment for atrial fibrillation, radiofrequency ablation and continued pharmacologic therapy maintained sinus rhythm in 93%.
