We present a 16-year-old patient with Wolff-Parkinson-White syndrome admitted with syncope and aborted sudden cardiac death. Electrocardiography showed only a short PR interval without a delta wave. The QRS transition zone was on V2 in the precordial leads. Twenty-four-hour ambulatory cardiac rhythm monitoring showed an obvious delta wave only at night-time. Electrophysiologic testing was performed and a right anteroseptal accessory pathway was ablated from the noncoronary aortic cusp. ECG after ablation showed sinus rhythm with right bundle branch block morphology, with no obvious change in the PR duration.
