What’s your differential diagnosis for this ECG?

Why does this matter?
We find ourselves in the COVID-19 era. This changes the differential diagnosis for several illnesses. This is an important ECG pattern for us to know.

My, what big inverted T waves you have!
This was a case report in JACC, a 21 year old man with sarcoidosis who had tapered steroids over the previous two months. He had 2 weeks of dyspnea on exertion and leg edema. Labs: Nt-proBNP 7737 pg/mL; hs-T-Troponin 24 ng/L (normal <14 ng/L). ECG is below.

Answer: There is a right bundle branch block pattern, pronounced T wave inversions in the early precordial and inferior leads, right axis deviation, and prolonged QTc. This indicates RV strain.

This patient did not have COVID-19, and a CT ruled out PE. He turned out to have worsening pulmonary sarcoidosis and pulmonary hypertension-induced RV remodeling, likely made worse by his recent steroid taper. The point of this ECG is to recognize RV strain. The first consideration should be PE. Once you rule that out, we can take a little more time to figure out the rest.

  • Give me he same patient several years older with a couple of CV risk factors (perhaps not even necessary) and if those deeply inverted T waves in V2 were as significant in V3, I would have called them wellens type B and had the patient sent for cath.

    I would have related the rest to LV dysfunction, which is fair

    Repeat ECGs show anything interesting?
