Abstract

Objective To study ST-segment deviation on predicting culprit artery or culprit lesion in acute myocardial infarction(AM/).Methods The study population included patients with AMI who subsequently underwent coronary angiography during hospitalization.Culprit artery and culprit parts were evaluated,and ST-segment characteristics were analyzed.Results A higher ST-segment elevation in leadⅢthan in leadⅡand ST-segment depression＞1 mm in lead aVL or lead I were highly sensitive(75%)and specific(100%)markers for right coronary artery-related AMI.ST-segment depression＞1 mm in leadⅡ,Ⅲand aVF was lowly sensitive(39%)and highly specific (93%)marker for the left anterior descending artery-related AMI.Conclusion The culprit artery or culprit lesion coutd be predicted by using electrocardiogram at admission.
