设计的人体植物神经功能检测系统中的软件部分系用编译BASIC语言和宏汇编语言编制,有较高的运算速度。它包括心率转换模块、滤波与频谱分析模块、绘图模块、面积计算模块、计算参数模块及呼吸信号处理模块。本系统可计算反映人体植物神经功能的心率功率谱、连续R-R间期的变异系数(CV)、标准差(SD)、差平方均值(MSSB)等多种参数。可用于研究不同呼吸模式对人体植物神经功能的影响。 The design of the human autonomic nerve function detection system software part compiled with BASIC language and macro assembly language, a higher computing speed. It includes heart rate conversion module, filter and spectrum analysis module, drawing module, area calculation module, calculation parameter module and respiratory signal processing module. The system can calculate the heart rate power spectrum reflecting human autonomic function, CV, SD and MSSB of continuous R-R interval. It can be used to study the effects of different breathing patterns on the autonomic function of the human body.
