睡眠剥夺状态下心率变异性变化的研究进展

睡眠剥夺可以导致自主神经功能紊乱，而自主神经功能对维持心血管系统的稳定至关重要。心率变异性（HRV）分析是目前较为准确的预测心脏自主神经功能的无创性方法。近年来大量的研究着眼于采用HRV对正常睡眠以及睡眠剥夺状态下心脏自主神经功能进行评价。急性以及慢性睡眠剥夺可以引起HRV时域分析与频域分析指标的明显变化，且HRV指标异常与心血管风险明显相关。本文对以上几个方面进行了综述，并对未来的研究前景进行了展望。

Research progress on sleep deprivation-induced heart rate variability changes

Sleep deprivation leads to disturbance of the autonomic nervous system, which plays an important role in maintaining the stability of the cardiovascular system. Heart rate variability (HRV) analysis is a non-invasive and reliable tool in evaluating the activities of cardiovascular autonomic nervous system. In recent years, many studies focused on the evaluation of cardiac autonomic modulation in conditions of normal sleep and sleep deprivation by means of HRV analysis. Both acute and chronic sleep deprivations were proved to evoke dramatic and complex changes in HRV time-domain and frequency-domain indices. The changes of HRV were closely related to risks of cardiac events. The present article reviewed the studies on the fields mentioned above and brought forward an agenda for future research.
