Bradycardia Pericarditis STEMI

ECG met STEMI criteria and was labeled STEMI by computer interpretation. This ECG shows a sinus bradycardia with a normal conduction pattern (normal PR, normal QRS, and normal QTc), normal axis, normal R-wave progression, normal voltages. Hypothermia can also produce bradycardia and J waves, with a pseudo-STEMI pattern.

Three months prior to this presentation, he received a pacemaker for severe bradycardia and syncope due to sinus node dysfunction. His EKG with worse pain now shows enough ST elevation to meet STEMI criteria. The undergraduate continues: This new EKG pattern is more suggestive of acute pericarditis. This EKG seems to lack it.

Here is his initial ED ECG: The R-wave in V4 extends to 33 mm, the computerized QTc is 372 ms The only available previous ECG is from one year ago, during the admission when he was diagnosed with pericarditis: 1 year ago ECG, with clinician and computer interpretatioin of pericarditis Normal 0 false false false EN-US X-NONE X-NONE What do you think?

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.

Here is his previous ECG: This was my interpretation of the first ECG: Sinus bradycardia with less than 1mm ST elevation in V4-V6, elevated compared to the previous ECG, suggestive of lateral MI. In patients with suspicion of acute MI who have any ST elevation, aVL is also a very useful lead to differentiate between pericarditis and MI.
