Answer

Atrial flutter rhythm itself is unstable and usually reverts either to atrial fibrillation or to sinus rhythm. It would be unusual but certainly not impossible for a patient to remain in stable chronic atrial flutter. A history of preexcitation syndrome (Wolff-Parkinson-White) indicates a need for caution; these patients are at risk for 1:1 conduction of the flutter waves, which can cause ventricular fibrillation.
