The ECG did not meet STEMI criteria, and the final cardiology interpretation was “ST and T wave abnormality, consider anterior ischemia”. There’s only minimal ST elevation in III, which does not meet STEMI criteria of 1mm in two contiguous leads. But STEMI criteria is only 43% sensitive for OMI.[1]

Written by Bobby Nicholson What do you think of this “STEMI”? or basilar ischemia. Second, although there is a lot of ST Elevation which meets STEMI criteria, especially in V3-4, the ST segment is extremely upwardly concave with very large J-waves (J-point notching). 2016 Nov;34(11):2182-2185.

Computer read: "Non-specific ST abnormality, consider anterior subendocardial ischemia" There are very poor R-waves in V1-V4 suggesting old anterior MI. Firstly, subendocardial ischemia does not localize on 12-Lead ECG. But the real question at hand is: Are these precordial ST-depressions a result of subendocardial ischemia?

When “spot diagnosing” precordial ST-depression I instinctively evaluate aVR for any corresponding ST-elevation to see if an emerging pattern of broad subendocardial ischemia can be appreciated, in which the ST-depression should be otherwise global and demonstrably maximal in Leads II and V5. However, in this context (i.e. is present.

Smith15, and PERFECT Study Author Group 1 Hennepin County Medical Center, 2 Minneapolis Medical Research Foundation, 3 Background : The Smith-modified Sgarbossa criteria (MSC) are frequently recommended for diagnosing acute coronary occlusion (ACO; STEMI-equivalent) in the setting of ventricular paced rhythm (VPR).

A prior ECG from 1 month ago was available: The presentation ECG was interpreted as STEMI and the patient was transferred emergently to the nearest PCI center. BOTTOM Line: It can at times be extremely challenging to distinguish between anterior ST elevation from a benign Brugada Phenocopy pattern vs an acute anteroseptal STEMI.

This strongly suggests reperfusing RCA ischemia. Troponins, echocardiogram An echocardiogram showed inferobasilar hypokinesis, further supporting a diagnosis of regional ischemia , likely of the area supplied by the RCA.
