摘　　要：目的探讨运动试验中变时性功能检测对冠心病的诊断价值。方法对68例冠脉造影者在平板运动试验中变时性功能指标的变化进行测量,将冠脉造影阳性(冠心病组)与冠脉造影正常组、冠心病组中ST段压低者与ST段压低伴变时性功能不良者进行对比分析。结果冠心病患者运动后最大心率、变时性指数以及运动后心率恢复明显低于冠脉正常组(P<0.05和P<0.01),ST段压低伴变时性功能不良诊断冠心病的敏感性、特异性和阳性预测值均比ST段压低明显增高(P<0.05和P<0.01)。结论平板运动试验中变时性功能变化的观察与分析,是诊断冠心病的一种新的、有价值的无创性方法。Objective To explore the diagnostic value of detecting chronotropic action in patients with coronary heart disease（CHD）. Methods Chronotropic action of the exercise test was detected in 68 who underwent performed coronary angiography（CA）. Patients with CHI） confirmed by CA were compared with those with normal CA. Them,among the patients with CHD,those with ST depression alone were compared with those who had both ST depression and chronotropic action incompetence.Results The maximum heart rate, chronotropic response index, and heart rate recovery after exercise were significantly lower in CHD group than in normal group（ P 〈 0.05 and P 〈 0.01）. The sensitivity, specificity and positive forecast value of ST depression together with chronotropic action incompetence were higher than those of ST depression alone （ P 〈 0.05 and P 〈 0.01）. Conclusions Detection of chronotropic action is a novel valuable noninvasive method for diagnosis of CHD.
