This is a value typical for a large subacute MI, n ormal value 48 hours after myocardial infarction is associated with Post-Infarction Regional Pericarditis ( PIRP ). As already mentioned, this patient could have post-infarction regional pericarditis from a large completed MI. Sinus tachycardia has many potential causes. Hammill SC.

Relationship between abnormal microvolt T-wave alternans and poor glycemic control in type 2 diabetic patients. Alternation in ST segment appearance ( or in the amount of ST elevation or depression ) — is often linked to ischemia. PMID: 35146844; PMCID: PMC9296802.

He has a history of known CAD, diabetes, and dyslipidemia. More Smith comment: it is true that ST depression (STD) due to subendocardial ischemia does not localize [it is usually diffuse ST depression, in multiple leads and not reciprocal to ST elevation in an opposite territory], this ST depression is different!

A middle-aged diabetic dialysis patient presented with 24 hours of nausea and vomiting associated with ~6 pound weight loss. Normal RBBB, no evidence of ischemia. Patients with completed, transmural infarct are also at risk for post-infarction regional pericarditis and myocardial rupture. He did have one episode of diarrhea.

The exception is with postinfarction pericarditis , in which a completed transmural infarct results in inflammation of the subepicardial myocardium and STE in the distribution of the infarct, and which results in increased STE and large upright T-waves. These findings together are more commonly seen with pericarditis.
