在这项研究中，我们探讨了变化的心电图（ECG）的变异性和复杂性的飞行恐惧症（N = 61）和匹配的非恐惧症对照组（N = 58）时，他们进行了一个节奏的呼吸任务，并暴露于飞行相关的刺激。与对照组相比，恐惧症患者的复杂性/熵值预期较低。恐惧系统的复杂性以及心率变异性（HRV）预计将通过暴露于恐惧刺激降低。多尺度，熵（MSE）分析显示，较低的熵值在恐惧症在起搏呼吸和曝光，和复杂性的损失，观察恐惧症在暴露于威胁的情况。本研究未发现预期的HRV降低。讨论的重点是区分变异性和复杂性措施的心输出量，并在该领域的焦虑症的MSE分析的有用性。(c)2006 Elsevier B. V.保留所有权利。
In this study we explored the changes in the variability and complexity of the electrocardiogram (ECG) of flight phobics (N = 61) and a matched non-phobic control group (N = 58) when they performed a paced breathing task and were exposed to flight related stimuli. Lower complexity/entropy values were expected in phobics as compared to controls. The phobic system complexity as well as the heart rate variability (HRV) were expected to be reduced by the exposure to fearful stimuli. The multiscale, entropy (MSE) analysis revealed lower entropy values in phobics during paced breathing and exposure, and a complexity loss was observed in phobics during exposure to threatening situations. The expected HRV decreases were not found in this study. The discussion is focused on the distinction between variability and complexity measures of the cardiac output, and on the usefulness of the MSE analysis in the field of anxiety disorders.
