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.

1 The ED is a fast-paced environment where patient stability and life-and-limb-threatening conditions are prioritized. The American Academy of Emergency Medicine has called effective, efficient, and safe pain management a “specialty-defining skill.” Opioid analgesia is appropriate for moderate to severe acute abdominal pain (Table 1).
