目的 分析12导联动态心电图(DCG)与平板运动试验(TET)诊断冠心病的价值。方法 回顾性分析我院140例拟诊断冠 心病患者的临床资料，所有患者均先后接受DCG与TET、选择性冠脉造影(CAG)检查，以CAG为金标准，评价DCG与 TET诊断冠心病的灵敏度、特异度、阳(阴)性预测值和Kappa值(一致性)，并比较两种方式的检出率。结果 DCG诊 断冠心病的灵敏度为0.957，特异度为0.625，准确度为0.930，阳性预测值为0.967，阴性预测值为0.556，Kappa 值为0.550，与CAG检查的一致性一般；TET诊断冠心病的灵敏度为0.946，特异度为0.875，准确度为0.940，阳性 预测值为0.989，阴性预测值为0.583，Kappa值为0.668，TET与CAG检查的一致性一般；DCG诊断冠心病的检出率为 91.00%，TET诊断冠心病的检出率为91.00%为88.00%，差异无统计学意义(P＞0.05)。结论 12导联动态心电图与平 板运动试验均可作为诊断冠心病的有效手段。

Objective To analyze the value of 12-lead dynamic electrocardiogram (DCG) and treadmill exercise test (TET) in the diagnosis of coronary heart disease. Methods The clinical data of 140 patients who were proposed to diagnose as coronary heart disease were retrospectively analyzed. All patients were given DCG and TET and selective coronary angiography (CAG). CAG was taken as the gold standard, and the sensitivity, specificity, positive (negative) predictive value and Kappa value (consistency) of DCG and TET were evaluated in the diagnosis of coronary heart disease, and the detection rates of the two methods were compared. Results The sensitivity, specificity, accuracy, positive predictive value, negative predictive value and Kappa value of DCG in the diagnosis of coronary heart disease were 0.957, 0.625, 0.930, 0.967, 0.556 and 0.550, and its consistency was general with the CAG. The sensitivity, specificity, accuracy, positive predictive value, negative predictive value and Kappa value of TET in the diagnosis of coronary heart disease were 0.946, 0.875, 0.940, 0.989, 0.583 and 0.668, and the consistency of TET and CAG was general. The detection rate of coronary heart disease by DCG was 91.00%, and the detection rate by TET was 88.00% (P>0.05). Conclusion Both 12-lead dynamic electrocardiogram and treadmill exercise test can be used as effective methods for diagnosing coronary heart disease.
