【摘要】 利用ＫＴＥＮＧ型双侧脑血流自动检测仪，测量５３ 例脑导纳图波形为陡直型的健康人和２５ 例波形为近弧型的脑动脉硬化患者以及１３ 例高血压患者的功率谱，并将健康组与患者组进行了对比分析。结果显示：患者组与健康组频域脑导纳图功率谱，在基频部分无显著性差异，Ｐ＞００５，而在谐频部分有显著性差异，Ｐ＜ ００５。提示，脑导纳图功率谱为分析头部血管性疾病提供了一种新方法。更多还原

【Abstract】 In this article the KT ENG automatic detector for bilateral cerebral blood flow was used to measure the power spectra of 53 healthy persons with steep waveshape brain admittance plethysmogram and 25 cerebral atherosclerotic and 13 hypertensive patients with nearly arcuate waveshape brain admittance plethysmogram.The results were compared and analysed between the healthy and the sick,showing that there was no significant difference in the basic incessant part ( P >0 05) but notable difference in harmonious incessant part ( P <0.05). It is suggested that the power spectra of brain admittance plethysmograpy provides a new method for the analysis of cerebrovascular disease.更多还原
