This is ischemic ST depression, and could be due to increasing tachycardia, with a heart rate over 130, but that is unlikely given that the patient is now complaining of crushing chest pain and that there was tachycardia all along. One would expect that the angiogram would show open arteries with normal TIMI-3 flow and culprit lesions.
