Myocardial Infarction with Paradoxical ST-segment Elevation Migration: A Case Study

We present the case of a 47-year-old man with chest pain whose electrocardiogram (ECG) revealed ST-segment elevation in different territories within one hour . The cardiac catheterization findings were consistent with the second ECG. The migration of ST-segment elevation may be due to various reasons, including aortic dissection, coronary vasospasm, thrombus migration, and pericarditis. However, in our case, limb lead reversal was the suspected cause of migration of ST-segment elevation. The accurate identification of ST-segment elevation is important to the cardiologist in order to determine the culprit vessel. Moreover, early reperfusion of the coronary artery is associated with better prognosis.
