动态心电图对心肌缺血的诊断效果及准确性研究

Study on the effect and accuracy of dynamic electrocardiogram in the diagnosis of myocardial ischemia

目的研究分析动态心电图对心肌缺血的诊断效果及准确性,分析临床应用价值。方法选取2019年1月—2020年1月就诊于茌平区人民医院的冠心病患者130例进行观察研究,随机分为观察组和对照组各65例,对照组采取常规心电图检测,观察组采用动态心电图检测,比较两组临床诊断结果,并以冠状动脉造影结果为临床诊断判别标准,判定两组患者临床诊断的准确性。结果观察组临床检测结果各项数据均优于对照组,差异均有统计学意义(P<0.05)。与冠状动脉造影结果进行比较,观察组临床诊断准确性为95.45%,明显高于对照组的71.70%,差异有统计学意义(P<0.05)。结论对冠心病患者采用动态心电图进行临床检测,可以更为有效地诊断患者有无心肌缺血情况,疾病诊断准确性较高,具有较高的临床检测和诊断应用价值。

Objective To study and analyze the diagnostic effect and accuracy of dynamic electrocardiogram in myocardial ischemia,and analyze the clinical application value.Methods A total of 130 patients with coronary heart disease treated in Chiping District People’s Hospital from January 2019 to January 2020 were selected for observation and study and randomly divided into observation group and control group,with 65 cases in each group.The control group was detected by routine electrocardiogram,and the observation group was detected by dynamic electrocardiogram.The clinical diagnosis results of the two groups were compared,and the coronary angiography results were used as the clinical diagnosis criteria to determ i n e the accuracy of cli n i cal di agn osi s of the two groups.Results Each data of cli n i cal test results of the observati on group were better than those of the con trol group,an d the di fferen ces were stati sti cally si gn i fi can t(P<0.05).Com pared wi th the results of coron ary an gi ography,the cli n i cal di agn osti c accuracy of the observati on group was 95.45%,whi ch was si gn i fi can tly hi gher than 71.70%of the control group,an d the difference was statistically significant(P<0.05).Conclusion Usi n g dyn am i c electrocardi ogram for clinical detection to patients with coronary heart disease could m ore effecti vely di agn ose whether pati en ts have m yocardi al i schem i a.The accuracy of di sease di agn osi s was hi gh,an d had hi gh cli n i cal detecti on an d di agn osti c appli cati on value.to determine the accuracy of clinical diagnosis of the two groups.Results Each data of clinical test results of the observation group were better than those of the control group,and the differences were statistically significant(P<0.05).Compared with the results of coronary angiography,the clinical diagnostic accuracy of the observation group was 95.45%,which was significantly higher than 71.70%of the control group,and the difference was statistically significant(P<0.05).Conclusion Using dynamic electrocardiogram for clinical detection to patients with coronary heart disease could more effectively diagnose whether patients have myocardial ischemia.The accuracy of disease diagnosis was high,and had high clinical detection and diagnostic application value.
