What do you recommend for atrial flutter?

Cardioversion: This is the standard of treatment and it is a quick and easy, noninvasive outpatient procedure.

Conversion: Atrial flutter, unlike atrial fibrillation, most often results in the atria beating at about 300 BPM with the ventricles beating at about 150. This rapid rate is annoying, difficult to slow with medication, and is best treated by converting the rhythm to normal (or to atrial fibrillation). This requires blood thinning and then special meds plus electrical cardioversion if the meds alone fail.
