脑电阻图是脑动脉硬化症的主要辅助诊断方法之一,如果配合功能试验检查则对判定脑动脉硬化的程度更有帮助。目前,国内常用的功能试验为口含硝酸甘油药物试验。体位改变试验也是脑电阻图功能试验之一,Handjiev已将体位改变试验的脑电阻图变化作为判定脑动脉硬化程度的一项指标。近年来,我们对110例脑动脉硬 Brain electrical resistance map is one of the main auxiliary diagnosis of cerebral arteriosclerosis, if combined with functional tests to determine the extent of cerebral atherosclerosis is more helpful. At present, the commonly used functional test for oral nitroglycerin drug test. The change of position test is also one of the functional tests of the brain resistance graph. Handjiev has taken the change of the brain resistance graph of the position change test as an indicator of the degree of cerebral arteriosclerosis. In recent years, we have 110 cases of cerebral arteriosclerosis
