动态心电图与常规心电图在老年无症状性心肌缺血诊断中的价值分析

Value Analysis on Dynamic Electrocardiogram and Routine Electrocardiogram in Diagnosis of Senile Silent Myocardial Ischemia

目的:研究动态心电图与常规心电图在老年无症状性心肌缺血(SMI)诊断中的价值。方法:选取2018年3月-2020年5月武威市凉州医院收治的48例老年SMI患者作为研究对象,患者均接受常规心电图、动态心电图检查。比较两种诊断方式的SMI检出情况、SMI各时间段发作情况、心律失常检出情况。结果:动态心电图SMI检出率高于常规心电图,差异有统计学意义(P<0.05)。48例老年SMI患者6:00~12:00发作率最高,20:00~24:00发作率最低。两种检测方式心房颤动检出率比较,差异无统计学意义(P>0.05);动态心电图束支传导阻滞、房性期前收缩、室性期前收缩检出率高于常规心电图,差异有统计学意义(P<0.05)。结论:动态心电图对老年SMI的检出率较高,可以特异性反映患者疾病发作情况,应用价值较高。

Objective:To study the value of dynamic electrocardiogram and routine electrocardiogram in the diagnosis of senile silent myocardial ischemia(SMI).Methods:A total of 48 elderly patients with SMI admitted to Liangzhou Hospital of Wuwei City from March 2018 to May 2020 were selected as the research objects.All patients were examined by routine electrocardiogram and dynamic electrocardiogram.The SMI detection situation,SMI onset in each time period,and the detection of arrhythmia of the two diagnostic methods were compared.Results:The SMI detection rate of dynamic electrocardiogram was higher than that of routine electrocardiogram,and the difference was statistically significant(P<0.05).The onset rate of 48 elderly patients with SMI was the highest between 6:00 and 12:00,and the lowest between 20:00 and 24:00.The detection rate of atrial fibrillation between the two detection methods showed no statistically significant difference(P>0.05);The detection rate of bundle branch block,premature atrial beats and premature ventricular beats by dynamic electrocardiogram was higher than that by routine electrocardiogram,and the difference was statistically significant(P<0.05).Conclusion:The dynamic electrocardiogram has a higher detection rate of senile SMI,and can specifically reflect the disease onset in patients,and has higher application value.
