T-wave to ST ratio is greater than 4 in lead V6, making pericarditis unlikely (also there were no symptoms of pericarditis). If there are no changes in aVL, it is highly unlikely to be inferior STEMI. Would you be certain that it is not STEMI? Sudden cardiac arrest associated with early repolarization.

As always, takotsubo cardiomyopathy and focal pericarditis can mimic OMI, but takotsubo almost never mimics posterior MI, and both are diagnoses of exclusion after a negative cath. The provider contacted cardiology to discuss the case, but cardiology "didn't think it was a STEMI, didn't think he needed emergent cath." Canto et al.

There is ST depression in II, III, and aVF that is concerning for reciprocal depression from high lateral STEMI in aVL, where there is some ST elevation. There is also ST depression in precordial leads, greatest in V3 and V4, concerning for posterior STEMI. The patient died is spite of resuscitative efforts. It is found on 1% to 3.5%

A middle aged patient who was 3 weeks s/p STEMI came from cardiac rehab where he developed some chest pain, dyspnea and weakness on the treadmill. There is no acute STEMI. This is diagnostic of recent, reperfused STEMI. This is diagnostic of recent, reperfused STEMI. Acute STEMI would have upright T-waves.

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?
