动态心电图诊断糖尿病性冠心病的效果研究

Effects of Dynamic Electrocardiogram on Diagnosis of Diabetic Coronary Heart Disease

目的研究动态心电图诊断糖尿病性冠心病的效果研究。方法选择2015年12月到2018年12月到医院就诊糖尿病患者84例,其中合并冠心病患者40例,未合并患者44例;所有患者均进行常规心电图及动态心电图检测。统计两种心电图检测冠心病的诊断效能,统计合并组及非合并组的平均心率(HVGHR)、24h正常RR间期标准差(SDNN)、相邻正常RR间期差值均方根(RMSSD)、相邻RR间期差值超过50ms个数占比(PNN50)。结果常规心电图的诊断准确率84.52%、灵敏度85.00%、特异度84.09%;动态心电图的诊断准确率94.05%、灵敏度95.00%、特异度93.18%;动态心电图诊断准确性高于常规心电图(P<0.05);两种心电图的灵敏度、特异度无统计学差异(P>0.05);合并组SDNN、RMSSD、PNN50水平均低于非合并组,HVGHR水平高于非合并组(P<0.05)。结论动态心电图诊断糖尿病性冠心病诊断效能较高。

Objective To study the effect of dynamic electrocardiogram in the diagnosis of diabetic coronary heart disease(CHD).Methods During the period from December 2015 to December 2018,84 diabetes patients who were diagnosed in the hospital were enrolled,including 40 patients with CHD and 44 patients without CHD.All patients underwent routine electrocardiogram and dynamic electrocardiography.The diagnostic efficiency of the two electrocardiograms for detecting CHD was statistically analyzed.The average heart rate(HVGHR),24 normal standard diviation of NN intervals(SDNN),adjacent normal root mean square difference(RMSSD),and ratio of adjacent RR intervals over 50 ms(PNN50)in combination group and non-combination group were statistically analyzed.Results The diagnostic accuracy,sensitivity and specificity of routine electrocardiogram were 84.52%,85.00%and 84.09%,respectively.The above indexes of dynamic electrocardiogram were 94.05%,95.00%and 93.18%,respectively.The diagnostic accuracydynamic electrocardiogram was higher than that of routine electrocardiogram(P<0.05).There was no significant difference in sensitivity or specificity between the two electrocardiograms(P>0.05).SDNN,RMSSD,and PNN50 levels in combination group were lower than those in non-combination group,while HVGHR level was higher than that in non-combination group(P<0.05).Conclusion The diagnostic efficiency of dynamic electrocardiogram is relatively higher for diabetic CHD.
