对北京、上海、哈尔滨、沈阳、武汉等５家医院的２９６例各期高血压病患者的脑电图、脑电地形图、经颅三维多普勒超声（ＴＣＤ）和ＣＴ进行对比。发现：高血压病不仅可导致心血管疾患，而且在发病的早期就已经引起脑功能和脑血流动力学的改变，这些改变可通过上述的功能性检查发现，而不能被ＣＴ等形态学检查所代替。同时还发现，各期高血压在这些检查中各有差异，与病情的发展成正相关。ＴＣＤ在反映高血压病的变化中最敏感，其次为脑电地形图和脑电图。这些指标对诊治高血压病、预防和防治脑血管病的发生具有重要价值。
EEG, EEG, TCD and CT in 296 patients with hypertension in 5 hospitals in Beijing, Shanghai, Harbin, Shenyang and Wuhan were compared. Found that hypertension not only causes cardiovascular disease but also causes changes in brain function and cerebral hemodynamics early in the disease that can be detected by the above functional tests and not by morphological examination such as CT Instead. Also found that various stages of hypertension in these tests have different, and the development of the disease is positively correlated. TCD is the most sensitive in reflecting the changes of hypertension, followed by EEG and EEG. These indicators of the diagnosis and treatment of hypertension, prevention and treatment of cerebrovascular disease has an important value.
