创伤后应激障碍（PTSD）的特征是心理生理异常，如基线心率改变和对各种刺激的高反应性或低反应性，这意味着唤醒调节功能障碍。心率变异性（HRV）已被确定为唤醒调节能力的重要标志。本研究的目的是研究在不同的情感条件下，PTSD的HRV，并探讨潜在的调节因素的作用。为了实现这一目的，向患有创伤后应激障碍（PTSD）的创伤暴露参与者（n = 26）、没有创伤后应激障碍（PTSD）的创伤暴露参与者（n = 26）以及非创伤暴露对照组（n = 18）呈现不同情绪效价的视频，同时记录心率变异性。PTSD组在基线（年龄校正）和不同情感条件下的HRV低于非创伤暴露对照组，这意味着副交感神经活动减少和反应调节不灵活。HRV与抑郁自评和状态分离呈负相关。(C)2011爱思唯尔有限公司版权所有。
Posttraumatic stress disorder (PTSD) is characterized by psychophysiological abnormalities, such as an altered baseline heart rate and either hyper- or hyporeactivity to a wide range of stimuli, implying dysfunctional arousal regulation. Heart rate variability (HRV) has been established as an important marker of arousal regulatory ability. The aim of the present study was to examine HRV in PTSD under different affective conditions and to explore the role of potential moderating factors. To meet this purpose, videos of varying emotional valence were presented to trauma-exposed participants with PTSD (n = 26), trauma-exposed participants without PTSD (n = 26), as well as non-trauma-exposed controls (n = 18) while HRV was recorded. The PTSD group showed lower HRV than non-trauma-exposed controls at baseline (corrected for age) and throughout different affective conditions implying decreased parasympathetic activity and an inflexible response regulation. There was a negative relationship between HRV and self-report of both depression and state dissociation. (C) 2011 Elsevier B.V. All rights reserved.
