目的探讨分析影响心电图平板运动试验结果的因素以及其临床应用价值。方法回顾性分析了2 a 412例临床疑诊为冠心病的患者行心电图平板运动试验检查结果。结果 412例平板运动试验共71例阳性,阳性率为17.2%,其中5例为假阳性(加做心得安试验,排除冠心病可能),假阳性率为7.0%,另有4例为假阴性,(加做冠脉造影检查,明确诊断为冠心病),假阴性率为1.2%。结论心电图平板运动试验对于筛查不典型或隐匿型冠心病是一种经济、简便、无创且准确性较高检查方法,但在操作时应尽量排除假阳性和假阴性因素的干扰。
Objective To explore the factors influencing the electrocardiogram treadmill exercise test results and its clinical value. Methods A retrospective analysis of 2 a 412 cases of clinical suspicion of coronary heart disease in patients with electrocardiogram treadmill exercise test results. Results A total of 71 cases of 412 treadmill exercise tests were positive, with a positive rate of 17.2%, of which 5 were false positives (plus an empiric test to rule out coronary heart disease). The false positive rate was 7.0% and the other 4 were false negative , (Plus coronary angiography, a clear diagnosis of coronary heart disease), false negative rate was 1.2%. Conclusion Electrocardiogram treadmill exercise test is an economical, simple, noninvasive and accurate method for the screening of atypical or occult coronary heart disease. However, the interference of false positive and false negative factors should be eliminated in the operation.
