    AbstractThe diagnosis of myocardial contusion in the setting of blunt trauma engenders much discussion and controversy-partly because of the lack of a gold standard for its identification other than histologic findings at autopsy. Furthermore, blunt cardiac trauma represents a spectrum of disorders ranging from transient electrocardiographic change to sudden death from myocardial rupture; hence, no single terminology exists to define such a wide range of scenarios. Here, we present 2 cases of electrocardiographic ST-segment elevation after high-speed motor vehicle crashes resulting in numerous injuries, including blunt chest trauma. Both patients demonstrated electrocardiographic ST-segment elevation, resulting from myocardial contusion and acute myocardial infarction.
