title: Association of transient abnormal Q-waves during exercise testing with a stenosis of the main stem of the left coronary artery.
abstract: Transient electrocardiographic changes resembling acute myocardial infarction, with Q-waves and ST-segment elevation, have been reported in a variety of clinical situations in which evidence for acute myocardial necrosis was not apparent. Such electrocardiographic changes resolved to normal within minutes. We report a case in which exercise testing induced a painless reversible electrocardiographic abnormality identical to acute anterior myocardial infarction, and subsequent angiography revealed a severe stenosis in the proximal left coronary artery. We suggest that patients presenting with this type of electrocardiographic exercise response should proceed to urgent coronary angiography.
