We who know ischemic ECGs know that really when T-wave inversion is specific for coronary thrombosis that it indicates reperfusion of the artery, not active occlusion. Learning Point: 1. For examples of such exceptions — See My Comment in the January 9, 2019 — August 22, 2020 — and June 30, 2023 posts in Dr. Smith's ECG Blog ).

The pain is described as located in the midsternal area, radiating to the right arm, described as 8-9/10 and worse with deep inspirations. In the evening, he became diaphoretic and complained of 9/10 continuous chest pain. If there is NO WMA, then it is not coronary occlusion, but if there IS one, then you still don't have a diagnosis.

And so it is wise to look at the coronary arteries. Here they are: Learning Points: 1. This ECG certainly looks like myocarditis, and was due to myocarditis, but missing acute coronary occlusion is not acceptable. In acute MI, the T-wave is large, and the T/ST ratio is high. This is much more typical of myocarditis.

My answer alleviated their concern for ACS and no further workup was done for ACS. 4 important features that indicate acute right hear strain: 1. looked at consecutive patients with PE, ACS, or neither.
