动态心电图对冠心病患者心肌缺血及心律失常的诊断价值

Diagnostic value of dynamic electrocardiogram for myocardial ischemia and arrhythmia in patients with coronary heart disease

目的探讨动态心电图对冠心病患者心肌缺血及心律失常的诊断价值。方法选取2020年5月至2022年8月在医院接受相关检查并确诊为冠心病的90例患者为研究对象,以平衡序贯法将其分为对照组和观察组,各45例。对照组接受常规心电图检查,观察组接受动态心电图检查。比较两组的检查结果。结果观察组的心肌缺血、心律失常阳性率及ST段抬高、压低检出率高于对照组,差异具有统计学意义(P<0.05)。两组不同类型心律失常检出情况比较,差异无统计学意义(P>0.05)。观察组的房性早搏成对、二三联律及室性早搏成对、二三联律检出率高于对照组,差异具有统计学意义(P<0.05)。观察组的超低频功率(ULF)、高频功率(HF)、低频功率(LF)及极低频功率(VLF)高于对照组(P<0.05)。结论动态心电图在冠心病心肌缺血及心律失常中的诊断价值较高。

Objective To explore the diagnostic value of dynamic electrocardiogram for myocardial ischemia and arrhythmia in patients with coronary heart disease.Methods A total of 90 patients who received relevant examinations and were diagnosed with coronary heart disease in our hospital from May 2020 to August 2022 were selected as the research objects.The patients were divided into control group and observation group by balanced sequential method,with 45 cases in each group.The control group received routine electrocardiogram examination,and the observation group received dynamic electrocardiogram examination.The examination results of the two groups were compared.Results The positive rate of myocardial ischemia and arrhythmia and the detection rate of ST segment elevation and depression in the observation group were higher than those in the control group,and the differences were statistically significant(P<0.05).There were no significant differences in the detection of different types of arrhythmia between the two groups(P>0.05).The detection rates of paired atrial premature beats,bigeminy and trigeminy of atrial premature beats and paired ventricular premature beats,bigeminy and trigeminy of ventricular premature beats in the observation group were higher than those in the control group,and the differences were statistically significant(P<0.05).The ultra low frequency(ULF),high frequency power(HF),low frequency power(LF)and very low frequency power(VLF)in the observation group were higher than those in the control group(P<0.05).Conclusion The dynamic electrocardiogram has high diagnostic value in myocardial ischemia and arrhythmia of coronary heart disease.
