The best answer is A. This patient is in the throes of a very large Myocardial Infarction. Acute current of injury (ST elevation) in V2 represents injury to the septum, V3 and V4 represent injury to the true anterior left ventricle, V5 and V6 the anterolateral wall. This infarction is due to occlusion of the proximal Left Anterior Decending Coronary Artery (LAD). Significant Q waves in I, aVL, V2-6 suggest extensive loss of myocardium has already occured.
