Ten patients with panic disorder and 10 matched control subjects were compared as to their blood pressure and heart rate during regular daily activity. Physiological responses were monitored by ambulatory recorder, and subjective reports of mood were collected. Data were analyzed controlling for activity and stress level of the subjects. Diastolic blood pressure emerged as a possible discriminatory factor between the groups. A trend for higher heart rate occurred in the panic group. In behavioral terms, panic patients tended to avoid anxiety-provoking situations, resulting in anxiety ratings comparable to those of the control group. Thus, recorded physiological differences between the groups may reflect heightened baseline autonomic activity in panic patients.
对10名惊恐障碍患者和10名匹配的对照受试者在日常正常活动期间的血压和心率进行了比较。通过动态记录仪监测生理反应，并收集情绪的主观报告。分析数据时控制了受试者的活动和压力水平。舒张压成为两组之间可能的鉴别因素。惊恐组出现心率较高的趋势。在行为方面，惊恐症患者倾向于避免引发焦虑的情况，导致焦虑评分与对照组相当。因此，两组之间记录的生理差异可能反映了惊恐症患者基线自主神经活动的增强。
