Left lateral wall infarction occurs as a result of occlusion of the circumflex coronary artery. On a 12-lead ECG, new Q waves and ST-segment T-wave changes are seen in leads I, aVL, V5, and V6. In reality, very few patients present with only lateral wall ECG changes. Often times some anterior wall leads (V3 and V4) may show evidence of injury or infarction.
