为了观察正常人脑血流图转折型者的脑血管弹性改变程度,探讨波型的演变规律,我们于1978年5月对58例转折型者作了脑血管弹性机能试验。被测对象在测试前均详细询问病史、体检和做辅助检查(查心电、眼底及胸部间摄和测胆固醇及血脂),凡体检及辅助检 In order to observe the degree of change of cerebrovascular elasticity of normal persons with cerebral blood flow diagram turning type and to explore the evolution of wave form, we conducted cerebral vascular elasticity test in 58 cases of turning type in May 1978. Subjects were asked in detail before the test history, physical examination and to do auxiliary examination (check ECG, fundus and chest photography and test cholesterol and lipids), where physical examination and auxiliary examination
