【摘要】 从基于加速度传感器的体动型频率自适应起搏器心率控制方法的研究入手,设计了一种运动--心率预测系统。系统的上位机和下位机之间通过蓝牙模块进行通讯。下位机完成人体加速度信号的采集、处理以及加速度信号向起搏心率信号的映射,同时完成加速度信号和心率信号的实时传输。上位机完成人体加速度信号和心率信号的实时显示和记录,并且通过对6个参数的分级设置实现对下位机的算法控制。应用运动--心率预测系统进行的验证实验结果表明,线性算法得到的映射起搏心率和实际心率的相关性比较好,线性比较显著(R2=0.787,P<0.001)。更多还原

【Abstract】 Focusing on the heart rate control mode of acceleration sensor based rate responsive pacemakers,this paper implemented the design of activity--heart rate prediction system.Bluetooth module was used as communication means in activity--heart rate prediction system,and the slave computer was used to complete the acceleration signal acquisition and processing,map from acceleration signal to the pacing rate signal,and achieve real-time transmission of acceleration signal and heart rate signal.The master computer fulfllled real-time display and recording of acceleration signal and heart rate signal,moreover,it achieved control function to the slave computer algorithm through classifoication of 6 parameters.The results of veriflcation experiment showed that there was a significant relation between mapping heart rate and actual heart rate using linear mapping algorithm(R2=0.787,P<0.001).更多还原
