A: Electrocardiography shows a short PR interval (96 msec) and QRS-complex widening (114 msec) with a delta wave. B: Electroencephalography shows 2-3 Hz frontal-dominant generalized polyspikes and wave discharges. C: Pedigree of the patient shows maternal inheritance traits. WPW: Wolff-Parkinson-White.

Electrocardiography revealed a short PR interval and a delta wave with QRS-complex widening, suggesting WPW syndrome (Fig. 1A). Abundant 2-3 Hz generalized spikes/polyspikes and wave discharges were found in an EEG examination (Fig. 1B). His maternal great-grandmother also had a hearing defect, and his aunt was diagnosed with epilepsy (Fig. 1C).
