摘要
目的探讨活动平板运动试验（TET）中U波倒置在冠心病诊断中的价值。方法拟诊或可疑冠心病患者52例，均接受冠状动脉造影及运动平板检查。分析平板运动试验时U波倒置与冠状动脉病变的关系。结果以传统标准判定运动试验的结果，呈阳性者58例，阳性率为71．6％；而以U波倒置为判定标准时，则阳性者为69例，阳性率达83．95％。两者经χ^2检验差异有统计学意义（P〈0.01）。结论运动试验中运用U波倒置来作为冠脉病变的诊断标准，可以提高冠心病的筛选诊断率。
Objective To estimate the value of inversion of wave U in treadmill ECG test （TET） in diagnosis of coronary heart disease （CHD）. Methods Fifty - two cases who are suspicious of CHD were adopted in this investigation,TET and coronary arteriongraphy were exerted to these patients and changes of wave U were record and the lesions of coronary were confirmed by coronary arteriongraphy. Results There are 58 cases of positive diagnosis in TET which account for 71.6% according to conventional criterion ,while the amounts of positive diagnosis were enhanced 69 cases account for 83.95% on the biases of inversion of wave U and the difference were significant （ P 〈0.01 ）. Conclusion Changes of inversion of wave U in TET is more sensitively to improve the monitor rate of the lesions of coronary heart disease than conventional standard.
