摘要:

目的 探讨应用动态心电图(AECG)的心率变异性(HRV)对儿童阻塞性睡眠呼吸暂停低通气综合征(OSAHS)初筛的可行性。方法 收集首都医科大学附属北京儿童医院2012年3月至9月间年龄3岁以上的睡眠打鼾儿童,在进行睡眠监测(PSG)的同时进行连续24h AECG监测。根据PSG结果分别作出有无OSAHS的诊断,通过比较OSAHS与非OSAHS患儿HRV的差异,通过受试者工作特性曲线(ROC)法得出敏感指标及临界值作为初筛标准。评价应用HRV初筛OSAHS的可行性。 结果 OSAHS患儿与非OSAHS相比,SDNNall day、SDANNall day、PNN50night、LF/HFnight及PNN50day-night差异均有统计学意义;用ROC法得到SDNNall day≤95.5 ms、SDANNall day≤80.5 ms、PNN50night≤24.6%、LF/HFnight≥0.845及PNN50day-night的绝对值≤24.55 ms为最佳初筛界值。联合应用5项指标(积分法)来初筛OSAHS,ROC曲线下面积(AUC)最大为0.695。结论 HRV作为评估OSAHS是否存在自主神经功能失调的指标,有望成为一种初筛OSAHS的方法。

Abstract:

Abstract: Objective To study the application of ambulatory electrocardiography to screen obstructive sleep apnea/hypopnea syndrome (OSAHS) in children was evaluated by time-domain and frequency-domain analysis of heart rate variability (HRV). Methods Totally 100 individuals underwent polysomnography and 24-h ambulatory electrocardiography simultaneously. Identify appropriate boundary of HRV parameters to diagnose OSAHS by using ROC curve. Evaluate the feasibility of screening for OSAHS by time-domain and frequency-domain analysis of HRV. Results SDNNall day, SDANNall day, PNN50night, PNN50day-night and LF/HFnight were significantly different in OSAHS group as compared with non-OSAHS group. Thresholds were set at SDNNall day≤95.5 ms, SDANNall day≤80.5 ms, PNN50night≤24.6, LF/HFnight≥0.845 and absolute PNN50day-night≤24.55 by using the ROC curve. The area under ROC curve (AUC) could reach 0.695 by uniting 5 parameters. Conclusion Time-domain and frequency-domain analysis of HRV is a useful method for OSAHS screening.
