Paramedic Education at Monroe Community College, Rochester, New York
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.
