The interventional cardiologist then canceled the activation and returned the patient to the ED without doing an angiogram ("Not a STEMI").

Corroborating this is the subtle ST depression in V2-V3 which is inappropriate for the normal QRS complex, and in the context of ACS, we have shown this is quite specific for posterior OMI. In the context of ACS, ST depression maximal in V1-V4 (rather than V5-V6) not due to a QRS abnormality is specific for posterior OMI.

Recall that, in the setting of ACS symptoms, ST depression that are maximal in leads V1-V4 (as opposed to V5 and V6) not attributable to an abnormal QRS complex is specific for OMI.
