Gastrointestinal Distention Masquerading as ST-Segment Elevation Myocardial Infarction

Abstract ST-segment elevation myocardial infarction (STEMI) is the most serious manifestation of acute coronary syndrome. A variety of noncardiac conditions can mimic STEMI on electrocardiography (ECG). We describe a case of gastrointestinal distention and ileus masquerading as STEMI on ECG and posits a mechanism for this effect. (Level of Difficulty: Intermediate.)
