高血压病的脑电图、脑电地形图与TCD、CT的对比研究

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。

The Contrast Study of EEG,BEAM and TCD,CT in Patients with Hypertension

The author together with coworkers from Beijing,Shanghai Ha'erbin,Shenyang and Wuhan,performed a contrast study among EEG,BEAM,TCDand CTin 296 cases of hypertension at different stages and found that hypertension not only resulted in vascular disorder of the heart and brain,but also gave rise to changes in the brain funtion and blood flow dynamics at the early stage of the onset. The changes could be revealed by EEG,BEAMand TCD,instead of CT.The author discovered that there were great differences in different stages of hypertension during the functional check,which had a parallel relationship with the patient's status of progress. Among these functional examinations,TCDshowed the highest sensitivity for reflecting the change in hypertension and followed by BEAMand EEGin a descending order. These indexes are of great value for the diagnosis and treatment of hypertension,as well as prediction of the blood vessel trouble.
