脑电阻图既可以反映头部搏动性血液供应情况,又可反映脑血管紧张度和弹性,是无创性检查脑血液动力学方法,已广泛应用于临床研究脑血管疾患。高原红细胞增多症患者常有头晕,头痛,记忆力减退,严重者可有恶心,呕吐,视神经乳头水肿,脑脊液压力升高。高原红细胞增多症的脑血液循环变化尚未见有报告,探讨脑电阻图变化对于了解高原红细胞症的脑血液循环及某些症状发生有一定意义。 Brain electrical resistance diagram can reflect the head pulsatile blood supply, but also reflects the cerebrovascular tone and flexibility, noninvasive examination of cerebral hemodynamics, has been widely used in clinical studies of cerebrovascular disease. Patients with high altitude polycythemia often dizziness, headache, memory loss, severe cases may have nausea, vomiting, papilledema, increased cerebrospinal fluid pressure. No changes have been reported in the changes of cerebral blood circulation in high altitude polycythemia. It is of some significance to explore the changes of cerebral resistance patterns in understanding cerebral blood circulation and some symptoms of plateau polycythemia.
