Atrial Flutter Mimicking Acute Myocardial Infarction
Keywords:atrial flutter, myocardial infarction, ST segment elevation, STEMI mimic
AbstractA 37-year old male came to the emergency room complaining of atypical chest pain of a few hours duration. Initial ECG displayed atrial flutter with 3:1 atrioventricular (AV) conduction with mostly pronounced inferior-wall but also diffuse ST-T changes suspect of acute ST elevation myocardial infarction (STEMI) (Figure, panel A) with already established inferior Q waves.
