摘要
【目的】比较心电图、高频心电图和运动平板试验在冠心病诊断中的意义。【方法】对100例心内科住院病人作选择性冠状动脉造影并造影前后2周内分别进行心电图、高频心电图、运动平板试验检查，以至少一支冠脉直径狭窄≥50％作为诊断冠心病的标准，比较冠心病组（60例）与非冠心病组（对照组，40例）的检测结果。【结果】冠心病组心电图、高频心电图和运动平板试验的阳性检出率均显著高于对照组（P〈0．01）；在三种检查方法中，冠心病组高频心电图与运动平板试验的阳性检出率无显著性差异（P〉0．05），但均显著高于心电图（P〈0．01）；对照组中，心电图、高频心电图的阳性检出率无显著性差异（P〉0．05），但均显著高于运动平板试验（P〈0．01）。【结论】运动平板试验能够对大多数的冠心病患者进行筛查，且对无冠心病者误诊率相对较低，应根据患者实际情况，正确选择或联合应用以上检查方法。
[Objective]To compare the diagnosis value among electrocardiogram（ECG）, high frequency electrocardiograph（HFECG） and treadmill exercise test（TET） for coronary artery disease （CAD） . [Methods] Each of CAD group（ n = 60） and control group（ n = 40） underwent ECG, H FECG, TET and selected coronary angiography（CAG）. CAD was defined as the presence of one or more vessels with 50% Luminal diameter narrow. [Results] The positive rate of EcG, HFECG and TET in CAD group were significantly higher than those in control group（ P〈0.01）. In three inspection methods, the positive rate of HFECG had no significant difference-in CAD group（ P〉0.05）, but was significantly higher than that of ECG （ P〈0. 01）. In the control group, the positive rate had no significant difference between ECG and HFECG（ P〉0.05）, but the positive rate of ECG and HFECG were significantly higher than that of TET（ P 〈0.01）. [Conclusion] Most patients with CAD can be screened by TET. The misdiagnosis rate of TET is relatively low in the people without CAD. According to the actual situation, the examination methods or the combination of above methods should be chosen correctly.
