This was his ECG. It was shown to me with worry for ischemic ST elevation, which is certainly possible from severe CO toxicity, or concomitant ACS. In fact, there is laboratory evidence that CO toxicity increases Plateletneutrophil aggregates and plasma myeloperoxidase (MPO) concentration and thus may precip
