Clinical Course The paramedic activated a “Code STEMI” alert and transported the patient nearly 50 miles to the closest tertiary medical center. Author continued : STE in aVR is often due to left main coronary artery obstruction (OR 4.72), and is associated with in-hospital cardiovascular mortality (OR 5.58). What do you see?

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.
