A 2-3 mm ST segment elevation seen on a post-operative ECG is significant because it is indicative of myocardial injury, which can occur due to various factors related to surgery. In the context of surgery, particularly cardiac or thoracic procedures, myocardial ischemia may arise from factors such as poor perfusion, increased myocardial oxygen demand, or use of certain anesthetic agents.

Elevated ST segments typically suggest that there is an active process affecting the myocardial tissue, and this observation should prompt further evaluation to determine the underlying cause and to implement appropriate management strategies. Recognizing ST segment elevation as a sign of potential myocardial injury is crucial to prevent complications and ensure the patient receives timely interventions if necessary.

Normal findings or arrhythmias do not usually present with such distinct ST segment elevations, making this specific elevation an important clinical feature that merits attention and further investigation in the post-operative setting.
