Int J Cardiol 2013 2. ST-elevation myocardial infarction after pharmacologic persantine stress test in a patient with Wellens’ syndrome. Single High-Sensitivity Cardiac Troponin I to Rule Out Acute Myocardial Infarction. Was this objective evidence of inducible ischemia accompanied by chest pain?

Followup ECG: No Change Absence of evolution is the best evidence against ischemia as the etiology. I was taught that the tell-tale sign of ischemia vs an electrical abnormality was in the hx, i.e. chest pain for the ischemia and potential syncope for brugada. Ischemia/infarction. It helps a little bit.

This ECG is diagnostic of diffuse subendocardial ischemia. Door to balloon time (DBT) was 96 minutes for 7 patients with ST elevation myocardial infarctions (STEMI) who had CT prior to PCI vs. 75 minutes for 11 patients who did not have CT, p=0.058. Conclusions: Head CT is common in NT-OHCA.

There is no ST depression in V6, II, III, or aVF, and no significant ST elevation in aVR, all confirming that the ST vector is not consistent with diffuse subendocardial ischemia, but rather a focal ST vector pointed at the posterior wall. There is sinus rhythm with normal QRS complex and ST depression in V2-V5, maximal in V3-V4.

Here is his ECG: There is no clear evidence of OMI or ischemia. This " imbalance of precordial T waves" is not seen very often — and in the “right” clinical setting, has been associated with recent OMI from a LCx culprit artery ( See Manno et al: JACC 1:1213, 1983 — and the July 17, 2013 post by Salim Rezaie in ALiEM ).

Due to the atypical and vague symptoms, the myocardial infarct was not initially diagnosed. At presentation he had a history of dyspnea for 6 days.
