Whenever there is tachycardia, I am skeptical of OMI unless it has led to severely compromised ejection fracction with cardiogenic shock. Supply-demand mismatch can cause ST Elevation (Type 2 STEMI). Also see these posts of Type II STEMI. Truly, the Marquette 12 SL algorithm correctly identifies this STEMI.

The paramedics diagnosis was "Possible Anterolateral STEMI." More proof that a huge STEMI may have normal or near normal initial troponin. Taken together, these findings suggest an ongoing extensive antero-lateral STEMI. I don't know what the device algorithm interpretation stated. The final angiographic result is very good.

See our other cases with similar patters, to burn this deep into your brain files: Smith : In my experience, these cases of LAD OMI with RBBB and LAFB are either about to arrest, post-arrest, and/or in cardiogenic shock. Acute chest pain, right bundle branch block, no STEMI criteria, and negative initial troponin.

. _ Here is the Queen of Hearts interpretation, appropriately reading STEMI equivalent, highlighting anterior and lateral leads with explainability, and even detecting reduced LVEF. The Cardiologist stated that the ECG did not show signs of STEMI, but rather NSTEMI, recommended serial ECGs and troponins, and cancelled the activation request.
