摘要
为验证Tv_1≥Tv_5诊断冠心病的价值,对136例冠脉造影病人的常规心电图进行分析,并与以造影显示冠脉狭窄≥75％为诊断冠心病的标准作对照。结果显示:Tv_2≥Tv_3诊断冠心病的敏感度为77.2％,特异度为61.2％,准确度为75.7％,阳性预测值为95.0％。显示这一标准比Tv_1≥Tv_5更有诊断价值,且Tv_1和Tv_2均≥Tv_5对严重冠心病诊断特异度更高,有重要诊断价值。
In order to study value of ECG TV1 taller than Tv5 in diagnosis of coronary heart disease, data of electrocardiogram were analysed in 136 patients who had undergone coronary angiography, with severity of coronary stenosis more than 75% as criterion for diagnosis of coronary heart disease. Results indicated that sensitivity, specificity, accuracy and positive predictive value of Tv2≥ Tv5 were 77. 2%, 61. 2%, 75. 7%, 95% respectively , and TV2≥Tv5 as criterion in diagnosis of coroanry heart disease was more significant than TV1≥Tv5 ?Re-suits indicated especialy that Tv2≥Tv5 accompanied with Tv1≥Tv5 had a higher specificity in diagnosis of severe coronary heart disease.
