Ischemia Pericarditis STEMI

Overall, this looks like one of the rare ECGs that is actually specific for pericarditis in my opinion. QOH versions 1 and 2 both say Not OMI, with high confidence, without any clinical context, despite the abnormal STE meeting STEMI criteria. Pericarditis maybe." There was no prior ECG for comparison.

This ECG is diagnostic of anterior STEMI. 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. However, look closely! Lessons: 1.

The ECG did not meet STEMI criteria, and the final cardiology interpretation was “ST and T wave abnormality, consider anterior ischemia”. There’s only minimal ST elevation in III, which does not meet STEMI criteria of 1mm in two contiguous leads. But STEMI criteria is only 43% sensitive for OMI.[1]

ECG met STEMI criteria and was labeled STEMI by computer interpretation. J waves can also be induced by Occlusion MI (5), STEMI mimics including takotsubo and myocarditis complicated by ventricular arrhythmias (6, 7), and subarachnoid hemorrhage with VF (8). Take home : Not all STEs are STEMIs or OMIs. What do you think?

Clinician and EKG machine read of acute pericarditis. While it is true that inferior MI has ST depression in aVL 99% of the time (Bischof and Smith), and that inferolateral ST elevation is the most common distribution for pericarditis, the ST elevation in V3 has "terminal QRS distortion (TQRSD)," (diagnostic of LAD occlusion).

This is a value typical for a large subacute MI, n ormal value 48 hours after myocardial infarction is associated with Post-Infarction Regional Pericarditis ( PIRP ). As already mentioned, this patient could have post-infarction regional pericarditis from a large completed MI. Sinus tachycardia has many potential causes.

This is a 45 yo male who had an inferior STEMI 6 months prior, was found to have severe LAD and left main disease, and was supposed to be set up for CABG a few weeks later, but did not follow up. But it could be anterior STEMI. 40% of anterior STEMI has upward concavity in all of leads V2-V6. is likely anterior STEMI).
