Résumé :

Body surface potential maps were recorded from 120 electrode sites in 236 normals (N), 114 patients with anterior MI (AMI) and 144 patients with inferior MI (IMI). At each time instant, the group-mean N map was subtracted in turn from the corresponding AMI and IMI maps; the resulting differences at each electrode site were standardized, producing discriminant maps for each bi-group comparison. Classification of patients based on the presence of one or more patterns typical in time and in location of their respective groups yielded 96% and 93% of correct assignment to AMI and IMI, respectively. Specificity was 94%.
