Case report shows ST-segment elevation following radiofrequency catheter ablation in WPW with left ventricular hypertrophy, suggesting lasting effects of electrotonic modulation.
A 47‐year‐old male with Wolff‐Parkinson‐White syndrome (WPW) and left ventricular hypertrophy (LVH) was admitted for transient loss of consciousness. Intracardiac electrophysiological examination identified a left posterior septal accessory pathway, which was successfully ablated via radiofrequency catheter ablation. Postoperative electrocardiogram (ECG) showed J–ST segment elevation in anterior leads V2–V4. At 2‐week follow‐up, the J point and ST segment elevation in leads V2–V4 had diminished but not fully resolved. Due to the electrotonic modulation mechanism, WPW patients may develop anterior ST‐segment elevation post‐ablation, and LVH may prolong the time for the ST segments to normalize.
