脑血流图是在头部通过微弱的高额电流描记颅内血流,随着心搏过程的变化而引起的电阻抗改变。从而反映脑血流供应情况和血管壁弹性状态的方法。我们于1986年对居住在厦门岛30年以上,85岁以后的老年人进行脑血流图检查,现分析如下。一、检测对象:1.躯干无显著畸形,无明显驼背等不良体型;2.神经系统基本正常,无偏瘫、老年性 Cerebral blood flow diagram is in the head through a weak high current tracings of intracranial blood flow, as the heartbeat process changes caused by electrical impedance changes. Thus reflecting the cerebral blood flow and vascular wall elasticity of the state of the method. We conducted cerebral blood flow tests on elderly people over the age of 85 who lived in Xiamen Island in 1986 and are analyzed as follows. First, the test object: 1 torso no significant deformity, no obvious humpback and other unhealthy body types; 2Normal nervous system, no hemiplegia, senile
