阻塞性睡眠呼吸暂停综合征患者的心率变异改变

HRV Change in Obstructive Sleep Apnea Syndrome

目的:了解阻塞性睡眠呼吸暂停综合征患者的心率变异改变。方法:对67例睡眠打鼾患者同步进行24小时动态心电图及多导睡眠图监测。根据PSG检测结果分为OSAS组和单纯鼾症组,比较组间低频峰(LF),高频峰(HF),低频峰与高频峰的比值(LF/HF),正常RR间期平均值及其标准差值(SDNN),正常RR间期差值均方根(rMSSD)。结果:OSAS组中,频域分析指标:LF,HF,均低于单纯鼾症组,LF/HF高于对照组,时域分析指标:SDNN,rMSSD均低于对照组。结论:OSAHS患者心率变异性降低。

Objective： To study the HRV change in OSAS.Methods： Polysomnography and synchronous 24-hour ECG monitoring were executed to 67 cases with snoring in sleep,and then were divided into 2 groups： OSAS group and Simply Snoring group.HRV parameters,such as LF,HF,LH/HF,SDNN,rMSSD,were compared between the 2 groups.Results： LF,HF,SDNN,rMSSD in OSAS group were lower than that in Simply Snoring group,but LF/HF was higher.Conclusion： The HRV reduced in OSAS.
