摘要
作者测量100例妇女心电图运动试验后即刻QTc间期。冠心病组50例运动后即刻QTc间期比静息时明显延长(P<0.001),比正常配对组50例则明显缩短(P<0.001)。以QTc间期延长≥0.01秒力阳性指标,与ST段压低比较,其敏感性可从42％提高至70％,特异性从66％提高至76％;如综合QTc间期与ST段标准加以判断时,可使敏感性、特异性分别增至74％、88％。
Fifty women with coronary heart disease(CHD)and 50 normal females were randomized in this study. All subjects underwent exercise testing to evaluate sensitivity and specificity of prolonged QTc interval and ST segment depression, The QTc interval in the CHD group and control group right away after exercise testing was evidently prolonged and evidently shortened respectively (P<0.001). In this study, we take the prolonged QTc interval (≥0.01″) as the positive criterion in diagnosing CHD of women. The QTc criterion manifested higher sensitivity(70％) and specificity (76％) than ST segment depression. When the combination of the two criteria is used togather for judgment, the sensitivity and specificity will be raised to 74％ and 88％ respectively.
