Coronary ischemia induced Wolf Parkinson White syndrome

A 60-year-old woman was admitted to cardiology clinic because of typical chest pain. The presenting electrocardiography (ECG) revealed sinus rhythm and T wave inversion on inferolateral wall. Her chest pain relapsed at second day of admission and electrocardiogram recorded during chest pain had ECG changes consistent with Wolf Parkinson White (WPW) syndrome. She underwent cardiac catheterization and borderline lesion was detected in proximal of left anterior descending artery and direct stent implantation was performed. This is the first case report in which acute ischemia may induce typical ECG changes of WPW in a patient with concealed WPW syndrome. We concluded that acute coronary ischemia may manifest concealed WPW syndrome.
