Data on the use of antiarrhythmic agents specifically to treat atrial flutter are limited. Most studies of antiarrhythmics agents and atrial fibrillation include some patients with atrial flutter (10-20%). (For more information on the use of antiarrhythmic agents, see Atrial Fibrillation.) In general, antiarrhythmics used to treat atrial fibrillation have been shown to be effective in fibrillation or flutter during a 6- to 12-month follow-up.
