Does the electrocardiographic pattern of "anteroseptal" myocardial infarction correlate with the anatomic location of myocardial injury?

Journal Article

The current electrocardiographic (ECG) definition of anteroseptal acute myocardial infarction (AMI) is a Q wave or QS wave > 0.03 second in leads V1 to V3, with or without involvement of lead V4. To verify whether there is a correlation between the ECG pattern of anteroseptal AMI and the location of an AMI, we compared ECG, echocardiographic, and cardiac catheterization findings of 80 patients who fit the traditional definition of anteroseptal AMI. We found that 48 of 52 patients (92%) who presented with ST elevation in leads V1 to V3 had an anteroapical infarct and a normal septum. The culprit narrowing was more frequently found (in 85% of patients) in the mid to distal left anterior descending artery. We conclude that there is no correlation and that the ECG pattern traditionally termed anteroseptal AMI should be called an anteroapical AMI; the term anteroseptal AMI should be defined as extensive anterior wall AMI associated with diffuse ST changes involving the anterior, lateral, and occasionally, inferior leads.
