本文对30例冠心病患者和30例正常人平板运动试验中的 R 波振幅改变与 ST 标准作了对比分析。统计分析表明,R 波振幅改变的敏感性和特异性均低于 ST 标准;阳性和阴性预检值与 ST 标准无差异性。结论:平板运动试验中的 R 波振幅改变不是诊断冠心病的可靠指标。
In this paper, 30 patients with coronary heart disease and 30 normal treadmill exercise test in the R wave amplitude changes and the ST standard made a comparative analysis. Statistical analysis showed that the sensitivity and specificity of R wave amplitude changes were lower than the ST standard; positive and negative pre-test value and the ST standard no difference. Conclusion: The change of R wave amplitude in treadmill exercise test is not a reliable indicator for diagnosing coronary heart disease.
