摘要
通过磁带式２４ｈ连续动态心电监测，对１８６例确诊心肌梗死连续病例及５０例非冠心病者进行Ｑ－Ｔｃ分析，并与传统ＳＴ段指标相比较。Ｑ－Ｔｃ延长检出心肌缺血的敏感性与特异性分别为９２．５％与９６．０％；ＳＴ段指标诊断心肌缺血的敏感性与特异性分别为６９．４％与１００％。两组敏感性差别有高度显著性（Ｐ＜０．０１）．两组特异性差别无显著性（Ｐ＞０．０５）。结果提示：Ｈｏｌｔｅｒ检测中Ｑ－Ｔｃ的延长能作为心肌缺血的判断指标之一。
Possible heterogeneity in immunogenetic aspects of IDDM was investigated by comparing the findings on relationship between HLA DQA1 52 Arg(+)and IDDM predisposition in three groups with different age of IDDM onset(group A≤14 year)group B 15￣30 year,group C≥31 year.Results showed that the frequency of HLA DQA1 52 Arg(+)in group A(87.5%)was higher than thar in control (53.9%, P <0.05)and in group B and C( P <0.05),the frequency of HLA DQA1 52 Arg(+)/Arg(+)phenotype in group A (75%)was higher than that in group C (23.1%, P <0.05).It was concluded that the contribution of HLA DQA1 52 arginine to IDDM susceptibility is heterogeneous,further study is necessary to clarify the immunogenetic entity of IDDM.
