目的：探讨惊恐障碍患者基底动脉血流对过度通气的反应。方法：应用经颅多普勒超声检测了16例惊恐障碍患者和8例正常对照者穿背心时和过度通气后的基底动脉血流。受试者在每个阶段对他们的头晕进行评分。结果如下：与正常对照组相比，惊恐障碍患者表现出更大的流速降低和更大的头晕增加。结论：惊恐障碍患者基底动脉对过度通气的敏感性更高，这表明惊恐发作期间神经系统症状的发展可能是一种机制。
Objective: The purpose of this study was to measure the response of basilar artery blood flow to hyperventilation in patients with panic disorder. Method: Transcranial Doppler ultrasonography teas used to measure basilar artery flow during vest and after hyperventilation in 16 patients with panic disorder and eight normal comparison subjects. The subjects rated their dizziness at each phase. Results: The patients with panic disorder demonstrated greater reduction in flow rates and greater increases in dizziness than the normal comparison subjects. Conclusions: The greater basilar artery sensitivity to hyperventilation shown by panic disorder patients suggests a possible mechanism for the development of neurological symptoms during panic attacks.
