Cardioversion, : Radio frequency ablation, medication, surgery... See this: http://www.Mayoclinic.Org/atrial-flutter/treatment.Html.

Depends... : Treatment of a flutter depends on the type of flutter (typical or atypical), whether it's the 1st episode, the age of the patient, the presence or absence of underlying heart disease, and patient's personal preferences (more medications vs. Procedural approach (ablation). Ablation is an excellent option for typical flutter. You should discuss this with your doctor or an electrophysiologist.

Depends: Atrial flutter is likely to turn into atrial fibrillation but the treatment is similar and depends on symptoms, onset and duration, other medical problems, and what the cause is thought to be. There are 2 main strategies. Rate control to slow down the rate. The other is rhythm control to get you into sinus. This can be done with medications or electricity. Anticoagulation may be indicated.
