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. The Queen of Hearts AI app will hopefully be FDA approved in Q1 of 2024. Figure-1: Comparison between the first 3 ECGs in today's case.
