中文摘要：
采用Hedges和Olkin根据效果量计算给出的方法，对国内8篇关于焦虑症患者心率变异性的研究进行元分析，深入系统地探讨以心率变异性为指标的自主神经系统（心血管系统）活动，焦虑症患者与正常群体的差异．结果发现：8项研究的效果量介于0．5344．83之间，8项研究的总效果量是1．24，总效果量95％的置信区间为0．18～1．06，表明心率变异性是区分焦虑症患者与正常群体自主神经变化的可靠指标，值得推广使用．
英文摘要：
A meta-analysis across multiple studies was conducted by the Hedges and Olkin method to compute effect sizes. Eight domestic studies focusing on correlation between heart rate variability and anxiety disorder were chosen for analysis. The autonomic nervous system was explored as indexed by heart rate variability in normal controls and in patients with anxiety disorders in depth and systematically. It was found that effect size of the 8 studies were between 0. 53 and 4.83. The total effect size was 1.24. Further, the 95% confidence interval of total effect size was from 0.18 to 1.06. This indicated that heart rate variability could be an effective indicator to distinguish healthy people from patients with anxiety disorders.
