A 34-year-old man presented to the outpatient clinic with syncope for 1 minute when he was working. He had no past medical and family history of sudden cardiac death. Electrocardiography (ECG) showed no remarkable findings. Follow-up ECG different from initial ECG was changed to type 1 Brugada ECG pattern. As time goes by, follow-up ECG was changed to type 2 Brugada ECG pattern. Although cause of syncope was assessed as Brugada syndrome, we performed coronary angiography to rule out ischemic heart disease. Coronary angiogram showed significant stenosis in the left main coronary artery (LMCA). Percutaneous coronary intervention with sirolimus-eluting stent was done at LMCA. He has been followed up for 1 year without any events. This is the first case of LMCA as syncope with Brugada type ECG in a young patient and it gives us the lesson that ischemic heart disease should be considered as the cause of syncope with Brugada type ECG.
