This report describes the case of a 41-year-old patient with Wolff-Parkinson-White syndrome and recurrent, highly symptomatic episodes of atrial fibrillation (with rapid heart rates of a mean of 250 beats/min) in whom transvenous catheter ablation of the accessory pathway was successfully performed in a relatively short time during the arrhythmia. The feasibility of an abbreviated approach to the relatively time-consuming ablation procedure in Wolff-Parkinson-White syndrome is discussed.
