Smith: If this is ACS (a big if), t his is just the time when one should NOT use "upstream" dual anti-platelet therapy ("upstream" means in the ED before angiography). History sounds concerning for ACS (could be critical stenosis, triple vessel), but differential also includes dissection, GI bleed, etc. Anything more on history?

Dedicated followers of the Smith ECG Blog know that the STD of true subendocardial ischemia does not localize, yet some of the examples listed below demonstrate the opposite, and were subsequently labeled “diffuse ischemia” or “generic subendocardial changes” as a diagnosis of convenience. However, the maximal STD in this case is V3.

He presented to the Emergency Department with a blood pressure of 111/66 and a pulse of 117. ACS and STEMI generally do not cause tachycardia unless there is cardiogenic shock. Then ACS (STEMI) might be primary; this might be cardiogenic shock. One must clearly rule out these processes before jumping on the ACS diagnosis.
