心率变异性在冠心病患者和冠心病合并高血压患者中应用价值的比较

The value of HRV in patients with CHD and CHD complicated with hypertension(EH)

目的探讨心率变异性(HRV)在冠心病和冠心病合并高血压患者中的应用价值。方法选取2014年5月至2014年11月在承德市中心医院行动态心电图(Holter)的检查患者共计105例。冠心病患者53例,冠心病合并高血压患者52例。采用时域分析和频域分析两种分析方法检测HRV,并进行对比分析。结果心率变异性时域分析法中,正常RR间期的标准差指数(SDNNIndex)在冠心病合并高血压组明显低于冠心病组(P<0.05);HRV频域分析法中,超低频功率频段(ULF)在冠心病合并高血压组明显低于冠心病组(P<0.05),差异均有统计学意义。结论冠心病合并高血压患者比单纯冠心病患者的自主神经损害严重,HRV测定可帮助了解其自主神经的缺失情况,对判断心脏病变程度及改善预后有重要意义。

Objective To compare the value of heart rate variability（ HRV） in patients with CHD and CHD complicated with hypertension（ EH）. Methods We selected 105 cases who checked Holter in the Central Hospital of from May 2014 to November 2014; 53 patients with CHD alone; 52 people with CHD patients with hypertension. There are two analytical methods for HRV indexes,time domain analysis and frequency domain analysis. Results For HRV time domain analysis method,SDNN index is lower for hypertension in CHD group than the value of simple CHD group,（ P〈0. 05）. For HRV frequency domain analysis,ULF value in patients with CHD hypertension group was lower than the value of simple CHD group（ P〈0. 05）. This difference was statistically significant. Conclusion The automatic dysfunction is more severe in patients with CHD complicated with hypertension than that with CHD only. Determination of HRV can help understand the lack of autonomic nerve situation. In judging degree of heart disease and improve prognosis.
