Is this inferor STEMI? Atrial Flutter with Inferior STEMI? Inferolateral ST elevation, vomiting, and elevated troponin The treating team did not identify the flutter waves and they became worried about possible "STEMI" (despite the unusual clinical scenario). The EM provider asked if the cardiologist thought it was a "STEMI."

A 56 year old male with a history of diabetes, dyslipidemia, hypertension, and coronary artery disease presented to the emergency department with sudden onset weakness, fatigue, lethargy, and confusion. At 2111, the troponin I peaked at 12.252 ng/mL (this is in the range of STEMI patients, quite high).
