Value of Ambulatory Electrocardiogram(AECG)and Routine Electrocar⁃diogram in Clinical Diagnosis of Myocardial Ischemia and Arrhythmia in Patients with Coronary Heart Disease

目的探究动态心电图(AECG)与常规心电图在临床诊断冠心病患者心肌缺血及心律失常中的价值。方法回顾性分析2018年7月—2019年7月该院收治的90例冠心病患者的临床资料,按照入院先后顺序将其分为对照组(n=44)和观察组(n=46),对照组采用常规心电图检测,观察组采用AECG检测方式,对比两组患者的检测结果、心律失常情况及心律失常检出率。结果观察组心肌缺血阳性率为86.96%明显高于对照组的52.27%,差异有统计学意义(χ^(2)=12.882,P<0.001);观察组心律失常阳性率为84.78%明显高于对照组的59.09%,差异有统计学意义(χ^(2)=7.399,P<0.05);观察组ST段抬高检出率明显优于对照组,差异有统计学意义(χ^(2)=4.358,P<0.05);观察组ST段抬低检出率明显优于对照组,差异有统计学意义(χ^(2)=6.425,P<0.05);观察组室内早搏、房性期前收缩、房性逸搏、室性心动过速、心房颤动、短阵室上速检出情况与对照组比较,差异无统计学意义(χ^(2)=0.787、1.341、0.569、0.046、0.079、0.167,P>0.05),但各项检出例数明显多于对照组。观察组二三联律中及成对中的室内早搏、房性期前收缩的检出率与对照组比较,差异无统计学意义(χ^(2)=0.518、0.014、0.023、0.023,P>0.05),但检出例数明显高于对照组。结论临床诊断采用AECG检测方式可有效提高冠心病患者心肌缺血及心律失常的检出率,为医生提供了准备的参考数据,值得推广和应用。

Objective To explore the value of dynamic electrocardiogram(AECG)and routine electrocardiogram in clinical diagno⁃sis of myocardial ischemia and arrhythmia in patients with coronary heart disease.Methods The clinical data of 90 patients with coronary heart disease admitted to the hospital from July 2018 to July 2019 were retrospectively analyzed,and they were di⁃vided into a control group(n=44)and an observation group(n=46)according to the order of admission.The conventional ECG test was used in the control group,and the AECG test in the observation group.The test results,arrhythmia status,arrhythmia detection rate and arrhythmia detection location of the two groups were compared.Results The positive rate of myocardial isch⁃emia in the observation group was 86.96%,which was significantly higher than 52.27%in the control group,and the difference was statistically significant(χ^(2)=12.882,P<0.001);the positive rate of arrhythmia in the observation group was 84.78%,which was significantly higher than 59.09%in the control group,and the difference was statistically significant(χ^(2)=7.399,P<0.05);the detection rate of ST segment elevation in the observation group was significantly better than that in the control group,and the difference was statistically significant(χ^(2)=4.358,P<0.05);the detection rate of ST segment elevation in the observation group was significantly better than that in the control group,and the difference was statistically significant(χ^(2)=6.425,P<0.05).Compared with the control group,there was no significant difference in the detection of indoor premature beat,atrial premature contraction,atrial escape beat,ventricular tachycardia,atrial fibrillation and short array supraventricular tachycardia in the ob⁃servation group(χ^(2)=0.787,1.341,0.569,0.046,0.079,0.167,P>0.05),but the number of detected cases in the observation group was significantly more than that in the control group,there was no statistically significant difference in the detection rates of indoor premature beats and atrial premature contractions between the observation group and the control group(χ^(2)=0.518,0.014,0.023,0.023,P>0.05).Conclusion AECG detection method can effectively improve the detection rate of myocardial isch⁃emia and arrhythmia in patients with coronary heart disease,and provide reference data for doctors,which is worthy of promo⁃tion and application.
