The key findings to look for on an ECG is the ST elevation which is characteristic of myocardial infarction. However, The major challenge is the differential between NSTE-ACS and non-cardiac chest pain. Diffuse ST elevation may point to the diagnosis of pericarditis. A serial ECG should be obtained to evaluate for continued or progression of myocardial injury over time.
