心力衰竭患者血管阻力增高,有证据表明,其神经体液活动增强.循环去甲肾上腺素水平升高究系交感神经活动增强抑或去甲肾上腺素合成、释放或代谢之改变,迄今未明.作者应用微电极技术直接记录静息状态下腓神经多条C类纤维的动作电位,经检波和积分后,输出平均电位信号,即交感神经传送 Vascular resistance in patients with heart failure increased, there is evidence that its neuroendocrine activity increased circulating norepinephrine increased sympathetic activity or norepinephrine synthesis, release or metabolic changes, so far unknown. The electrode technology directly records the action potentials of multiple C fibers of the peroneal nerve under resting state, and after detection and integration, outputs an average potential signal, that is, sympathetic nerve transmission
