心率变异性在冠心病患者和冠心病合并糖尿病患者中应用价值的比较

摘要

目的：探讨心率变异性（ HRV）在冠心病和冠心病合并糖尿病患者中应用价值的比较。方法选取2012年5月至2013年11月在承德市中心医院行动态心电图的检查患者共计98例，其中冠心病组49例，冠心病合并糖尿病组49例。采用时域分析和频域分析两种分析方法检测心率变异性。结果心率变异性时域分析法中rMSSD在冠心病合并糖尿病组低于单纯冠心病组，差异有统计学意义（ P <0.05）。结论冠心病合并糖尿病患者比单纯冠心病患者的自主神经损害严重。%Objective To compare the value of heart rate variability( HRV)in patients with CHD and CHD complicated with mellitus di-abetic. Methods 98 cases examined the dynamic electrocardiogram in the Central Hospital of Chengde City from May 2012 to Nov. 2013. They were divided into CHD group and CHD complicated with mellitus diabetic group,each group included 49 cases. The heart rate variability was de-tected with time domain and frequency domain. Results rMSSD with time domain was lower in CHD complicated with mellitus diabetic group than that in CHD group. Conclusion The automatic dysfunction is more severe in patients with CHD complicated with mellitus diabetic than that with CHD only.
