For the most part, morbidity and mortality result from complications of rate (eg, syncope and congestive heart failure [CHF]). In patients with atrial flutter, the risk of embolic occurrences approaches that seen in atrial fibrillation. Patients with Wolff-Parkinson-White syndrome who develop atrial flutter can develop life-threatening ventricular responses and therefore should be considered for catheter ablation of their accessory bypass tract.
