CPR was initiated immediately. If this is ACS with Aslanger's pattern , the ST depression vector of subendocardial ischemia (due to simultaneous 3 vessel or left main ACS) is directed toward lead II (inferior and lateral). It was reportedly a PEA arrest; there was no recorded V Fib and no defibrillation.

A middle-aged male with h/o CAD and stents presented with typical chest pressure. It is highly associated with proximal LAD occlusion or severe left main ACS and with bad outcomes. Here is his ECG: The resident was alarmed at the "ST elevation in III with reciprocal ST depression in aVL" Are you alarmed? This is a very common misread.

But if they do present: The very common presentation of diffuse STD with reciprocal STE in aVR is NOT left main occlusion , though it might be due to sub total LM ACS, but is much more often due to non-ACS conditions, especially demand ischemia. Beware crescendo angina in patient with known CAD ST Elevation in aVR Case 7.

In total, he received approximately 40 minutes of CPR and 7 defibrillation attempts. The patient was transferred immediately for angiogram which revealed no significant CAD, and no intervention was performed. Learning Points: The myocardium doesn't know the etiology of OMI (ACS, spasm, dissection, embolus, etc.),
