心血管系统的机能如心率的快慢与血压的高低,在人体内是受中枢神经系统和体液因素的严格控制,而通过植物神经及其释放的递质实现其调节作用的。心血管系统植物神经功能异常,势必引起心率和血压的变化。反之,通过一些机能实验和药物试验,人为地改变心率和血压,观察其变化过程,又可推断植物神经功能是否正常。本文对近年来常用的简便易行的非创伤性检查方法、指标及其原理作一简介。 Cardiovascular system functions such as heart rate and blood pressure levels in the human body is subject to the central nervous system and fluid factors strictly controlled by the autonomic and its release of neurotransmitters to achieve its regulatory role. Cardiovascular system autonomic dysfunction, is bound to cause heart rate and blood pressure changes. On the contrary, through a number of functional experiments and drug tests, artificially change the heart rate and blood pressure, observe the process of change, but also to infer whether the autonomic function is normal. In this paper, simple and easy to use in recent years non-invasive inspection methods, indicators and their principles to make an introduction.
