Changes in Electrocardiogram from Inferior Myocardial Infarction to Anterior Myocardial Infarction

Abstract

We describe a patient who developed acute chest pain and ST-segment elevation in the inferior leads on electrocardiography. In his control electrocardiography after 15 min, ST-segment elevation was observed in the anterior leads. Cardiac catheterization showed that there was wraparound left anterior descending artery and an occlusion in the proximal region. The occlusion was resolved by typical ballooning. To our knowledge, simultaneous ST elevations in anterior and inferior leads have been reported in the literature; however, in our case, with serial electrocardiographic (ECG) records, we realized that inferior ST-segment elevation altered to anterior ST-segment elevation. This indicates the importance of serial ECG records in emergency departments to explain the mechanism.
