This case was recently posted by Tyron Maartens on Facebook EKG club (he agreed to let me post it here), with the following clinical information: "42 year old male with two weeks of intermittent chest discomfort, awoke 4 hours prior to this ECG with a more severe, heavy chest pain (5/10). Both support acute anterior STEMI.

A 40-something male presented with dyspnea and left arm numbness, and perhaps some chest tightness, for 1 1/2 hours. This is all but diagnostic of STEMI, probably due to wraparound LAD The cath lab was activated. Therefore this is " Transient ST Elevation Unstable Angina." Why is this important? JACC 2016;67:1531.

This appears to be a classic Wellens' ECG, Pattern A, with terminal T-wave inversion in V2-V4, preserved R-waves, and it appears to be Wellens' syndrome, as it occurred after resolution of typical angina pain. Wellens' syndrome represents the aftermath of an unrecorded occlusion (STEMI) with spontaneous reperfusion.

Here is his ED ECG at triage: Obvious high lateral OMI that does not quite meet STEMI criteria. He was given aspirin and sublingual nitro and the pain resolved.

Thus, the patient does not (yet) get a formal diagnosis of MI and must be called unstable angina unless further troponins return above the 99th percentile. The patient said his chest pain was 4/10, down from 8/10 on presentation. On the basis of unresolved angina, cardiology decided to perform rescue PCI. of the time.

While this ECG is negative for “posterior STEMI”, the resolution of anterior ST depression (accompanied by the troponin elevation) confirms posterior OMI with spontaneous reperfusion. The second opportunity to make the diagnosis and expedite angiography was missed because the ECG never met STEMI criteria and continued to be labeled ‘normal.’

When total LM occlusion does present with STE in aVR, there is ALWAYS ST Elevation elsewhere which makes STEMI obvious; in other words, STE is never limited to only aVR but instead it is part of a massive and usually obvious STEMI. All are, however, clearly massive STEMI. This is her ECG: An obvious STEMI, but which artery?

It is equivalent to a transient STEMI. Not much, but studies of STEMI and NonSTEMI show that about 70% of those diagnosed with STEMI have a peak troponin I above 10 ng/mL and that about 70% of those diagnosed with NonSTEMI have a peak troponin I below 10 ng/mL. Again, cath lab was not activated. Int J Cardiol. 2016;207:341–348.
