I'm seeing elevation in v1-v2, depression in v4-v6, inverted T waves throughout, left ventricular hypertrophy(probably from the htn going untreated, possibly a smoker). I would call this a stemi from the diagnostics available because of the elevation greater than one mm, reciprical changes, and the signs of ischemia(even though the symptoms are atypical). As for STEMI mimics....Pericarditis? Am I way off base with my findings or am I in the ballpark? I just started working with a service that actually has and utilizes 12 leads lol.
