This meets "STEMI criteria" However, there is very high voltage, with a very deep S-wave in V2 and tall R-wave in V4. The morphology is not right for STEMI. My interpretation: LVH with secondary ST-T abnormalities, exaggerated by stress, not a STEMI. This is very good evidence that the ST elevation is not due to STEMI.

This has been termed a “STEMI equivalent” and included in STEMI guidelines, suggesting this patient should receive dual anti-platelets, heparin and immediate cath lab activation–or thrombolysis in centres where cath lab is not available. aVR ST segment elevation: acute STEMI or not? aVR ST Segment Elevation: Acute STEMI or Not?

The receiving emergency physician consulted with interventional cardiology who stated there was no STEMI. However the patient continued to have chest pain and bedside ultrasound showed hypokinesis of the septum with significantly reduced LVEF. Is there STEMI? The patient continued having chest pain. Leave it alone. Bigger et al.
