作者们对84例正常人,冠心病心肌缺血组100例心肌梗塞组100例的Ptfv_1值进行了调查及分析,结果如下: 1、84例正常人的Ptfv_1值全部为直立或>—0.02mm·S.这与国內资料提出的正常人Ptfv_1值是相符合的。 2、冠心病心肌缺血组100例中有43例Ptfv_1值(?)9.02mm·S(占43%)。作者们认为,当Ptfv_1值异常增大时,如能排除其它心脏疾患及技术误差,对诊断冠心病的特异性是较高的。 3、二级梯双倍运动试验与Ptfv_1值的对比结果如下:运动试验阴性组89例中有6
The authors investigated and analyzed the Ptfv_1 values of 100 normal and 100 myocardial infarction patients with myocardial infarction in 84 normal subjects and their patients with myocardial infarction. The results were as follows: The Ptfv_1 values of 1,84 normal subjects were all upright or> -0.02 mm · S. This is consistent with the normal Ptfv_1 values proposed by domestic sources. 2, Coronary heart disease myocardial ischemia group of 100 cases, there are 43 cases of Ptfv_1 value (?) 9.02mm S (43%). The authors believe that the specificity of the diagnosis of coronary artery disease is high if the other abnormalities in the heart and the technical errors can be excluded when the Ptfv_1 value is abnormally increased. 3, double ladder double exercise test and Ptfv_1 value comparison results are as follows: 89 cases of negative exercise test group of 6
