及临床意义 目的探討惊恐障碍患者心理特征和心率变异性的表达及临床意义。方法选 取广东省人民医院2013年6月～2014年12月接收的惊恐障碍患者60例为研究 组，另选取同时期于广东省人民医院健康体检的60例健康人员为对照组，两组 均采用心理问卷调查并借助心率变异性频谱对其心率变异性进行分析、对比。结 果研究组患者均存在不同程度的焦虑，与对照组比较差异有统计学意义（P＜ 0.05）；对照组R-R间期标准差（SDNN）、间隔5 min间期标准差（SDANN）、 相邻RR间期差异≥50 ms百分数（PNN50）、相邻R-R间期差值均方根（RMSSD） 以及频域分析高频功率（HF）、低频功率（LF）、极低频功率（VLF），低高频功 率比（LF/HF）等指标水平均高于研究组，差异有统计学意义（P＜0.01）。结论惊 恐障碍患者心理状态不佳，影响其心率变异性，应根据患者的实际情况采取相关 措施以改善预后。 [Abstract]Objective To discuss the expression and clinical significance of psychological characteristics and heart rate variability in patients with panic s Sixty patients with panic disorder treated by Guangdong Provincial People′s Hospital from June 2013 to December 2014 were lected as the study group，and another sixty healthy people for physical examination in Guangdong Provincial People′s Hospital during the same period were lected as the control the two groups were given psychological questionnaire，and the heart rate variability was compared and analyzed by heart rate variability s The patients in the study group had different level of anxiety，and the differences were statistically significant compared with tho in the control group （P＜0.05）.The indexes such as R-R interval standard deviation （SDNN），interval 5 min interval standard deviation （SDANN），adjacent to the diversity of R-R was greater than or equal to 50 ms percentage （PNN50），root mean square difference of the adjacent R-R interval （RMSSD）high frequency （HF），low frequency power （LF）， extremely low frequency power （VLF），low frequency power contrast high frequency （LF/HF）in the control group were higher than tho in the study group， with significant differences （P＜0.01）.Conclusion The m感谢老师的作文
ental state of panic disorder patients is not good，which affects the heart rate variability，and the relative measures should be taken according to the actual situationof the patients to improve the prognosis.[Key words]Panic disorder；Psychological characteristics；Heart rate variability；Nervi vagus；Sympathetic nerve 惊恐障碍（panic disorder，PD）是焦虑症急性发作期，主要是指反复出现出 汗、震颤、心悸等自主神经症状，患者多伴有失控、濒临死亡等强烈感受，考虑 问题时总会对可能出现的结果产生恐惧，典型临床症状表现为患者PD发作时存 在不可忍受的失控感及濒死感，多数伴有胸痛、心悸不适、过度换气、呼吸急促、 出汗、头晕、手足发麻及颤抖等症状，以上症状持续时间为5～20 min，可自行 缓解或突然性发作[1]。相关研究表明，PD患者病情的发展与其心理特征存在较 大关联，患者发病时多处于心理应激状态，超过机体可耐受程度后容易发展为心
