Smith : This is classic for pulmonary embolism (PE). Acute pulmonary embolism was confirmed on CT angiogram: The patient did well. See our other acute right heart strain / pulmonary embolism cases: A man in his 50s with shortness of breath Another deadly triage ECG missed, and the waiting patient leaves before being seen.

There is also STE in lead III with reciprocal depression in aVL and I, as well as some subendocardial ischemia pattern with STD in V5-V6 and STE in aVR. Aslanger's is a combination of acute inferior OMI plus subendocardial ischemia, and due to the ischemia vectors , it has STE only in lead III. Moreover, there is tachycardia.

But there was some doubt as to whether it might be pericarditis because of the ST elevation in I and II, without ST depression in III. Add that to "sharp" pain and a 33 year old, and it is easy to convince yourself that this is, indeed, pericarditis. This is a good sign for myocardial infarction and does not happen in pericarditis.

In terms of ischemia, there is both a signal of subendocardial ischemia (STD max in V5-V6 with reciprocal STE in aVR) AND a signal of transmural infarction of the inferior wall with Q wave and STE in lead III with reciprocal STD in I and aVL. The rhythm is atrial fibrillation. The QRS complex is within normal limits.

They include myocardial ischemia, acute pericarditis, pulmonary embolism, external compression due to mass over the right ventricular outflow tract region, and metabolic disorders like hyper or hypokalemia and hypercalcemia. According to a recent systematic review and meta-analysis, spontaneous type 1 ECG had 2.4%

Normal RBBB, no evidence of ischemia. Patients with completed, transmural infarct are also at risk for post-infarction regional pericarditis and myocardial rupture. LV aneurysm puts them at risk for a mural thrombus, which puts them at risk for embolism, especially embolic stroke. R-waves of of normal height.

Both of these are very suggestive of " No-Reflow ," or poor microvascular reperfusion due to downstream embolization of microscopic platelet-fibrin aggregates. More likely, the patient had crescendo angina, with REVERSIBLE ischemia for 48 hours that only became potentially irreversible (STEMI) at that point in time. Re-occlusion 2.
