Electrocardiogram on admission (Fig. 1) revealed what appeared to be a short PR interval and a wide QRS, with slurring of the initial portion of the QRS consistent with a delta wave, indicating ventricular pre-excitation, compatible the previous diagnosis of Wolff-Parkinson-White Syndrome.
ECG after ablation, demonstrating normal PR, absence of delta wave, and normal QRS duration.
