Correlation of polarcardiographic criteria for myocardial infarction with arteriographic and ventriculographic findings (substantiation of transmural and presentation of non-transmural criteria)

摘要: Summary Sensitivity and specificity of polarcardiographic criteria for myocardial infarction were compared with those electrocardiographic in 108 patients chest pain syndromes who referred coronary arteriography left ventriculography. With the combination total occlusion at least one artery abnormal systolic contraction part ventricle as best available documentation disease, sensitivity 70% 67%, respectively, using 80% 73% criteria, both anterior inferior infarction. Another criterion—rightward shift R latitude 10 msec after onset QRS—occurred concurrently vessel 16 17 (94%) in, four whom this was only objective evidence infarction, three there no manifest abnormality wall contraction. This criterion is considered nontransmural probably subendocardial layer near apex ventricle. When such added, increased to 84%, decreased equal that (67%).
