A 75-year-old man was admitted to our hospital in January 2010 for evaluation of syncope and abnormal ECG. ECG showed type 1 ST elevation in lead V(1) and he was diagnosed as Brugada syndrome. During cardiac catheterization, baseline coronary angiography was normal, but intracoronary ergonovine maleate induced spasms of the right and left coronary arteries concomitant with chest pain and ST elevation on ECG. J waves were accentuated or newly developed. Soon after an intracoronary injection of nitroglycerin, chest pain was relieved and ischemia-induced J wave disappeared and the ST segment returned to the same morphology as baseline. Extrastimuli induced ventricular fibrillation. He received an implantable cardioverter-defibrillator. He was also treated with Ca antagonist and isosorbide dinitrate and has had an uneventful course for 5 months.
