摘要
为探讨慢性阻塞性肺部疾病与心率变异性的关系 ,对24例慢性阻塞性肺部疾病和24例对照组进行心率变异性分析 ,并观察其与第1s用力呼气量的相关性。结果显示 :慢性阻塞性肺部疾病患者的SDNN、SDANN、SDNNIndex、rMSSD、PNN50 均明显低于对照组 (P<0.05) ,且第1s用力呼气量与上述时域指标呈高度正相关 (r=0.61～0.89,P<0.01)。提示心率变异时域指标反映慢性阻塞性肺部疾病的严重程度 ,有临床参考意义。
To explore relations between chronic obstructive pulmonary disease(COPD) and analysis of heart rate variability(HRV),24 patients with COPD and 24 controls were analysed by HRV.Correlation analysis between force exhale volume in first second (FEV1s) and indexes of HRV was observed.Results appeared that indexes of HRV(SDNN,SDANN,SDNN Index,rMSSD,PNN 50)in COPD patients were all apparently lower than that of control group(P<0.05).Significant cor _ relations were found between FEV1s and indexes of HRV(r=0.61～0.89,P<0.01). It certificated indexes of HRV reflect severity in COPD patients.That was clinical significant.
