目的：本研究的目的是评估是否高频心率变异性（HF-HRV）在清醒时的宁静和在担心预测增加睡眠障碍的压力lifestive.Methods：一项纵向研究随访22个人从定义明确的时期较低和较高的压力进行。HF-HRV在清醒时的宁静和在低压力期间的焦虑诱导的反应进行了测量。睡眠障碍进行了评估，使用匹兹堡睡眠质量指数（PSQI）和失眠严重程度指数（ISI）在低压力和高压力periods.Results：在低压力和高压力时期，较低的HF-HRV在担心与更大的PSQI分数。重要的是，较低的HF-HRV在担心感应前瞻性预测更大的增加PSQI评分从低压力到高stress.Conclusion：HF-HRV在担心可能代表的指数的脆弱性，压力引起的睡眠障碍。(C)2015 Elsevier B.

Objective: The aim of this study was to evaluate whether high-frequency heart rate variability (HF-HRV) during waking restfulness and during worry predicts increases in sleep disturbances in response to a stressful life event.Methods: A longitudinal study following up 22 individuals from well-defined periods of lower and higher stress was conducted. HF-HRV during waking restfulness and in response to a worry induction was measured during a low-stress period. Sleep disturbances were assessed using the Pittsburgh Sleep Quality Index (PSQI) and the Insomnia Severity Index (ISI) during low-stress and high-stress periods.Results: During both the low-and high-stress periods, lower HF-HRV during worry was associated with greater PSQI scores. Importantly, lower HF-HRV during the worry induction prospectively predicted greater increases in the PSQI score from the low-stress to the high-stress periods.Conclusion: HF-HRV during worry might represent an index of vulnerability to stress-induced sleep disturbances.
