Another ECG was recorded after the nitroglycerine and now without pain: All findings are resolved. No other symptoms.

The ECG did not meet STEMI criteria, and the final cardiology interpretation was “ST and T wave abnormality, consider anterior ischemia”. 1] But there are multiple other abnormalities that make this ECG diagnostic of Occlusion MI, localized likely to the right coronary artery: 1. But are there any other signs of Occlusion MI?

EKG, labs, and a CXR are interpreted by the EP as normal. An unknown EP reviews the report, determines that there is no reason to notify the patient, and documents nothing. It wasn’t, so you weren’t called, nor did the doc need to document anything. This patient’s history was either poorly taken or poorly documented.
