With the history of Afib, CTA abdomen was ordered to r/o mesenteric ischemia vs ischemic colitis vs small bowel obstruction. Systematic Assessment of the ECG in Figure-1: My Descriptive Analysis of ECG findings in Figure-1 is as follows: Sinus tachycardia at ~110/minute. The patient had mild but diffuse abdominal tenderness.

The axiom of "type 1 (ACS, plaque rupture) STEMIs are not tachycardic unless they are in cardiogenic shock" is not applicable outside of sinus rhythm. 2) Tachycardia to this degree can cause ST segment changes in several ways. Sometimes you must correct the rhythm to see what lies underneath. Is this inferor STEMI?

As in all ischemia interpretations with OMI findings, the findings can be due to type 1 AMI (example: acute coronary plaque rupture and thrombosis) or type 2 AMI (with or without fixed CAD, with severe regional supply/demand mismatch essentially equaling zero blood flow). The rhythm is rapid AFib.

We can see enough to make out that the rhythm is sinus tachycardia. Tachycardia is unusual for OMI, unless the patient is in cardiogenic shock (or getting close). A bedside ultrasound should be done to assess volume and other etiologies of tachycardia, but if no cause of type 2 MI is found, the cath lab should be activated NOW.
