The patient was brought to the ED and had this ECG recorded: What do you think? Cardiac arrest #3: ST depression, Is it STEMI? Confirmation of sinus tachycardia should be easy to verify when the heart rate slows a little bit ( as the patient's condition improves ) — allowing clearer definition between the T and P waves.

Notice on the right side of the image how the algorithm correctly measures STE sufficient in V1 and V2 to meet STEMI criteria in a man older than age 40. As most would agree, this ECG shows highly specific findings of anterolateral OMI, even with STEMI criteria in this case. Thus, this is obvious STEMI(+) OMI until proven otherwise.

This doesn’t meet STEMI criteria so in the current paradigm there’s no urgency to getting an angiogram. The initial ECG suggested either subacute or reperfused inferoposterior occlusion and clearly does not meet traditional STEMI criteria. Discharge diagnosis was ‘STEMI’, even though no ECG ever met STEMI criteria.

But because there was no new ST elevation, the ECG was signed off as “STEMI negative” and the patient waited to be seen. But the ECG still doesn’t meet STEMI criteria.

There is sinus rhythm with minimal STE in V1-V3, not meeting STEMI criteria. However, this STE is definitively abnormal in the setting of a normal QRS complex and hyperacute T-wave morphology in V2. The delay between OMI and STEMI sometimes causes unacceptable loss of myocardium or worse.
