A 50-something man presented in shock with severe chest pain. The patient was in clinical shock with a lactate of 8. There is an obvious inferior posterior STEMI(+) OMI. Results Of 149 patients with inferior STEMI , 43 (29%) had RVMI and 106 (71%) did not. He appeared gray in color, with cool skin.

The following are the KEY clinical and ECG features that establish the diagnosis of W ellens ' S yndrome : There should be a history of prior chest pain that has resolved at the time the defining ECG is obtained. The Chest Pain required for the definition of Wellens' Syndrome occurred at the time of coronary occlusion.

This 51 yo male complained of chest pain, then had a v fib arrest. He was in cardiogenic shock. As you will see, this results in the discovery of ST elevation in V2-V4 and I and aVL, diagnostic of anterolateral STEMI. The patient died 8 hours later of cardiogenic shock.

The conventional machine algorithm interpreted this ECG as STEMI. Taking a step back , remember that sinus tachycardia is less commonly seen in OMI (except in cases of impending cardiogenic shock). See this post of RV MI with both McConnell sign and "D" sign: Inferior and Posterior STEMI. Both were wrong.

A man in his 60's presented after 4 days of chest pain, with some increase of pain on the day of presentation. Exact pain history was difficult to ascertain. Thus, this is BOTH an anterior and inferior STEMI in the setting of RBBB. How old is this antero-inferior STEMI? There was some SOB. How acute is it?

The patient in today’s case is a previously healthy 40-something male who contacted EMS due to acute onset crushing chest pain. The pain was 10/10 in intensity radiating bilaterally to the shoulders and also to the left arm and neck. The ECG shows obvious STEMI(+) OMI due to probable proximal LAD occlusion.

Just the fact of chest pain and highly elevated troponin is enough to activate the cath lab, but here you can see just how subtle hyperacute T-waves can be. Troponin T peaked at 2074 ng/L (very high, typical of OMI/STEMI). Post PCI the patient became gravely hypotensive and "shocky". The LV EF was 57% at formal echo.

A middle aged man had off and on chest pain for 2 weeks, then 2 hours of more severe and constant pain. When the ST vector is primarily posterior, the diagnosis is usually posterior STEMI. Here was his ED ECG, which was identical to the prehospital ECG. He did not get prehospital activation. What do you think?

Then the notes mention "cardiogenic shock" but without any reference to a cardiac echo or to a chest x-ray. Now chest pain free. Cardiologist note says: "Elevated troponin explained by type II MI due to her shock." Trop T now very high, well into the range one sees with a STEMI; very unusual in type II MI.

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?

This was my response: If it is the right clinical situation, such as acute chest discomfort, it looks like proximal left anterior descending occlusion with right bundle branch block and left anterior fascicular block. Because of the tachcardia, I would expect her to be very poor left ventricular function and maybe Cardiogenic shock.
