通过对353人运动前后R波振幅改变的结果分析,作者认为运动试验引起R波振幅的改变,对诊断冠心病有一定意义。R波振幅与ST段的改变相结合,可提高冠心病的检出率。但不宜单独使用。
Through the analysis of the change of R wave amplitude before and after exercise of 353 people, the author thinks that the change of amplitude of R wave caused by exercise test is of certain significance for the diagnosis of coronary heart disease. The combination of R wave amplitude and ST segment changes can increase the detection rate of coronary heart disease. But it should not be used alone.
