Abstract

Abstract : Pre-excitation syndrome can either mimic or mask myocardial infarction, making the diagnosis of acute myocardial infarction difficult. Herein, we report the case of a male patient with Wolf-Parkinson-White (WPW) syndrome who presented to our emergency department with severe chest pain. Non-ST-elevation myocardial infarction was suspected because of cardiac enzyme elevation and abnormal ST-T changes identified through electrocardiography. The patient underwent percutaneous coronary intervention; a left anterior descending artery stenotic lesion was dilated, and drug-eluting stents were implanted. One month later, he underwent successful radiofrequency catheter ablation for his accessory pathway and tachycardia. We present the series of electrocardiographic ST-T abnormalities to raise awareness of the value of diagnosing myocardial injury early in patients with WPW syndrome.
