They had difficulty describing their symptoms, but complained of severe weakness, nausea, vomiting, headache, and chest pain. They described the chest pain as severe, crushing, and non-radiating. Altogether, this strongly suggests inferolateral OMI, particularly in a patient with acute chest pain.

The patient presented with chest pain. I was taught that the tell-tale sign of ischemia vs an electrical abnormality was in the hx, i.e. chest pain for the ischemia and potential syncope for brugada. Only 5-18% of ED patients with chest pain have a myocardial infarction of any kind. Is it Brugada pattern?
