摘　　要：目的分析慢性肺源性心脏病患者的心率变异性改变的临床意义。方法经动态心电图、血气分析检查,选取肺心病缓解期、急性期与正常受试者各42例,采用时域法分析其HRV的改变。结果肺心病组HRV均较对照组降低,且重症肺心病随血氧分压下降、二氧化碳分压升高,各参数下降更明显。结论肺心病患者HRV的改变在预测其心电变化指导临床治疗提供了重要的指标。Objective To analyze the clinical significance of the changes of chronic pulmonary heart rate variability.Methods The measures of electrocardiogram,blood gas analysis and HRV changes were compared among the patients at stable and acute stage of pulmonary heart disease（n=42） and with normal subjects（n=42）,by using.In comparison pulmonary heart disease group showed more decrease in HRV chayes and severe decline in pulmonary heart disease with in blood oxygen pressure,and more increase in carbon dioxide partial pressure.Conclusion The changes in HRV in patients with pulmonary heart disease in predicting changes in the ECG provides important clinical indicator for its treatment.
