目的探讨平板运动试验联合动态心电图检查在冠心病诊断中的应用效果。方法对150例疑似冠心病的患者进行平板运动试验和动态心电图检查,并行冠状动脉造影诊断冠心病,根据诊断结果分析平板运动试验和动态心电图检查的效果。结果全组行冠状动脉造影后诊断为冠心病113例。经分析,动态心电图检查敏感性为68.14%(77/113),特异性为81.08%(30/37)。平板运动试验敏感性为73.45%(83/113),特异性为83.78%(31/37)。结论动态心电图检查不能排除冠心病,还需结合临床实践及联合平板运动试验来提高冠心病的诊断率,以此减少假阴性的发生,最大程度的减少临床误诊和漏诊。
Objective To investigate the effect of treadmill exercise test combined with ambulatory electrocardiogram in the diagnosis of coronary heart disease. Methods 150 patients with suspected coronary heart disease were subjected to treadmill exercise test and ambulatory electrocardiogram examination. Coronary heart disease was diagnosed by coronary angiography. The treadmill exercise test and ambulatory electrocardiogram were analyzed according to the diagnostic results. Results The whole group was diagnosed as coronary heart disease after coronary angiography in 113 cases. After analysis, Holter test sensitivity was 68.14% (77/113), specificity was 81.08% (30/37). The sensitivity of treadmill exercise test was 73.45% (83/113) and the specificity was 83.78% (31/37). Conclusions Holter monitoring can not exclude coronary heart disease. Combined with clinical practice and combined treadmill exercise test, the diagnostic rate of coronary heart disease should be increased to reduce the incidence of false negatives and minimize the misdiagnosis and missed diagnosis.
