常规心电图与12导联动态心电图对老年冠状动脉粥样硬化性心脏病的诊断价值比较

Comparison of the value of electrocardiogram and 12-lead dynamic electrocardiogram in diagnosis of elderly patients with coronary atherosclerotic heart disease

目的比较常规心电图与12导联动态心电图(AECG)对老年冠状动脉粥样硬化性心脏病(简称冠心病)的诊断价值。方法选取2018年1月至2019年1月在南阳市中心医院治疗的85例老年冠心病患者,将其分为两组。对照组45例,进行常规心电图检查;观察组40例,进行12导联AECG检查,比较两组患者心肌缺血、心律失常的检出率以及冠状动脉病变检出率。结果观察组心肌缺血检出率[87.5%(35/40)]明显高于对照组[53.33%(24/45)],差异有统计学意义(χ^2=11.64,P<0.05)。观察组左右束支阻滞、房室阻滞、室性早搏二三联律、成对及房性早搏二三联律、成对检出率均明显高于对照组(P<0.05)。观察组冠状动脉单支、多支病变检出率均明显高于对照组(P<0.05)。结论对冠心病患者进行12导联AECG检查可提高心肌缺血、心律失常及冠状动脉病变检出率,具有较高的临床价值。

Objective To compare the diagnostic value of electrocardiogram and 12-lead AECG in elderly patients with coronary heart disease. Methods Eighty-five elderly patients with coronary heart disease who were treated in Nanyang Central Hospital from January 20 to January 1919 were divided into two groups. In the control group, 45 patients underwent routine electrocardiogram examination;40 patients in the observation group underwent 12-lead dynamic eletrocardiogram(AECG) examination. The detection rate of myocardial ischemia and arrhythmia and the detection rate of coronary lesions were compared between the two groups.Results The detection rate of myocardial ischemia in the observation group was 87.5%(35/40), which was significantly higher than that in the control group [53.33%(24/45)], the difference was significant(χ~2=11.64,P<0.05). The detection rates of left and right bundle branch block, atrioventricular block, premature ventricular beats, paired and premature atrial beats in the observation group were significantly higher than those in the control group(P<0.05). The detection rate of single and multiple coronary artery lesions in the observation group was significantly higher than that in the control group(P<0.05). Conclusions 12-lead AECG examination in patients with coronary heart disease can improve the detection rate of myocardial ischemia, arrhythmia and coronary artery disease, and has high clinical value.
