Correlation between the admission electrocardiogram and regional wall motion abnormalities as detected by echocardiography in anterior acute myocardial infarction

We correlated ST elevation in various leads on admission and regional dysfunction in 132 patient with first anterior acute myocardial infarction using echocardiography. ST elevation in leads I and a VL and II, III and aVF was not associated with a specific pattern of regional dysfunction. Basal anterior and septal regional dysfunction were seen more often in patients with ST elevation in V1 (49 vs. 25%, p = 0.006; 35 vs. 17%, p = 0.048, respectively). Patients with ST elevation in V2 had more regional dysfunction of the apical inferior region (84 vs. 53%; p = 0.01). ST elevation in V5 and V6 was not associated with more apical or lateral wall motion abnormalities. ST elevation in lead V1 in anterior myocardial infarction is associated with a high incidence of regional dysfunction of the basal anterior, anteroseptal and septal regions.
