Inferior ST segment depression as a useful marker for identifying proximal left anterior descending artery occlusion during acute anterior myocardial infarction.

摘要: To determine whether or not ST segment deviation on admission electrocardiograms can identify patients with anterior acute myocardial infarction due to proximal left descending artery occlusion, the magnitude and location of elevation depression were compared between occlusion (group A, n = 47) those distal B, 59). in each inferior leads was significantly greater group A than B. The incidence > 1 mm (II; 81% vs 27%, III; 85% 54%, aVF; 87% 47%, P all B (77% 22%, lead aVL higher (66% most valuable for identifying sensitivity 78% specificity). In contrast, maximal V2 alone had a low diagnostic value (43% 86% specificity, 66% 53% respectively). conclusion, this study indicates that analysis is useful occlusion.
