ECG diffuse subendocardial ischemia

Diffuse subendocardial ischemia manifested by prominent ST depressions in leads I, II, aVL, aVF, and V2 to V6, with ST elevation in aVR. A prolonged PR interval (0.28 sec) is also present. The findings also raise the possiblitity of severe multivessel or left main coronary artery disease.

Normal electrocardiogram showing normal sinus rhythm at a rate of 75 beats/minute, a PR interval of 0.14 seconds, a QRS interval of 0.10 seconds, and a QRS axis of approximately 75°.
