Atrial Flutter Masquerading as an ST-segment-elevation Myocardial Infarction in a Patient with Dextrocardia.

Electrocardiogram (ECG) findings suggestive of an ST-segment-elevation myocardial infarction (STEMI) often lead to emergent left heart catheterization. Occasionally, non-coronary conditions mimic ECG findings of STEMI, resulting in an increased risk and expenses from emergent transportation and procedures. In this report, we describe diagnostic and management strategies for a case of 1:1 atrial flutter in a patient with dextrocardia presenting as a STEMI.
