慢性肺源性心脏病患者24小时心率变异性的研究

The study of heart rate variability in patients with chronic pulmonary heart disease

目的 :研究男性慢性肺源性心脏病患者的心率变异性。方法 :46例健康男性 ,34例男性慢性肺源性心脏病患者 ,行 2 4h动态心电图记录 ,作时域和频域分析。结果 :慢性肺源性心脏病病人的高频 (HF)、低频 (LF)、NN5 0计数占总R -R间期的百分比 (pNN5 0 )、每 5min正常R -R间期标准差的平均值 (SDANN)均下降 ,其中严重的慢性肺源性心脏病患者下降更为显著。结论 :男性慢性肺源性心脏病患者存在植物神经功能紊乱 ,病情严重程度也与植物神经功能相关。

Objective:To study variability of heart rate in patients with chronic pulmonary heart disease.Method:Twenty\|four hour Holter monitoring were performed in 46 male healthy volunteers and 34 cases of chronic pulmonary heart disease who were divided into groups according to the severity of their heart failure.Results:The HF,LF,pNN50 and SDANN were decreased in the chronic pulmonary heart disease cases in comparing to the normal group.These values were the lowest in the severe chronic pulmonary heart disease group.Conclusion:The autonomic nervous function of the chronic pulmonary heart diseasemale sufferers differs from that of normal people.It is possible that the changes of autonomic nervous function of chronic pulmonary heart disease sufferers are related to the severity of chronic pulmonary heart disease.
