Abstract : The culprit lesion of acute myocardial infarction could be predicted by electrocardiogram findings. However, we experienced some cases with coronary angiographic finding in the area of ST-T elevation that was different from that predicted. The lambda-like J wave could be caused by ischemia although the mechanism has not been fully elucidated. We report a case of acute myocardial infarction that showed discrepancy between ST-T elevation with lambda-like ischemic J wave in a broad area and coronary angiographical finding of diagonal branch occlusion.
