摘要
目的:探讨动态心电图QTc间期联合运动平板试验诊断冠心病心肌缺血的价值。方法:选取昆山市第一人民医院2019年1月—2022年12月收治的108例疑似冠心病心肌缺血患者,均行运动平板试验、动态心电图检查。以冠脉造影诊断结果为金标准,对比以上两种方法诊断冠心病心肌缺血的效能。结果:108例疑似冠心病心肌缺血患者经冠脉造影检查,阴性30例,占27.78%,阳性78例,占72.22%。动态心电图QTc间期诊断为阴性共有20例,阳性51例,运动平板试验诊断为阴性共有25例,阳性50例,动态心电图QTc间期联合运动平板试验,诊断为阴性共有29例,阳性62例。动态心电图QTc间期联合运动平板试验诊断冠心病心肌缺血的敏感度为79.49%,特异度为96.67%,准确度为84.26%,联合诊断的敏感度、准确度均高于动态心电图QTc间期、运动平板试验单一诊断,联合诊断的特异度高于动态心电图QTc间期单一诊断,差异均有统计学意义(P<0.05)。结论:与单一诊断相比,动态心电图QTc间期联合运动平板试验诊断冠心病心肌缺血的价值更高,可为临床诊断提供可靠的心电学依据。
Objective:To investigate the diagnostic value of dynamic electrocardiogram QTc interval combined with exercise plate test in myocardial ischemia of coronary heart disease.Method:A total of 108 patients with suspected myocardial ischemia of coronary heart disease admitted to the First People's Hospital of Kunshan City from January 2019 to December 2022 were selected,and exercise plate test and dynamic electrocardiogram were performed in all patients.The diagnostic results of coronary angiography as the gold standard,the efficacy of the above two methods in diagnosing myocardial ischemia of coronary heart disease was compared.Result:108 patients with suspected myocardial ischemia of coronary heart disease were examined by coronary angiography,of which 30 cases were negative,accounting for 27.78%,and 78 cases were positive,accounting for 72.22%.20 cases were negative and 51 cases were positive diagnosed by dynamic electrocardiogram QTc.25 cases were negative and 50 cases were positive diagnosed by exercise plate test.29cases were negative and 62 cases were positive diagnosed by dynamic electrocardiogram QTc interval combined with exercise plate test.The sensitivity,specificity and accuracy of dynamic electrocardiogram QTc interval combined with exercise plate test in diagnosing of myocardial ischemia of coronary heart disease respectively was 79.49%,96.67% and 84.26%.The sensitivity and accuracy of combined diagnosis were higher than those of dynamic electrocardiogram QTc interval and exercise plate test single diagnosis,the specificity of combined diagnosis was higher than that of dynamic electrocardiogram QTc interval single diagnosis,the differences were statistically significant(P<0.05).Conclusion:Compared with single diagnosis,dynamic electrocardiogram QTc interval combined with exercise plate test has higher value in diagnosing of myocardial ischemia of coronary heart disease,and can provide reliable electrocardiology basis for clinical diagnosis.
