摘　　要：一种以数字信号处理器(DSP)为核心,具有实时检测、无线传输和24小时心电数据连续记录功能的多功能Holter系统。在该系统中,通过EASI导联系统模块采集心电信号,然后采用小波变换算法对心电信号进行实时特征提取,并将心电数据存入MicroSD卡实现24小时心电数据记录;或者通过Zigbee无线传输模块将心电数据传输到电脑进行远程实时监测及十二导联心电数据的推导。A DSP based multi-functional hoher system is introduced. The hoher system has 24-hours continuous recording of ECG, real-time detection, and wireless transmission function. The ECG signals are acquired by EASI lead system module, then processed by quadratic differential wavelet transformation algorithm for feature extraction. The data of ECG signals are saved to MicroSD card or transmitted to computer by Zigbee module for remote real-time monitoring and derivation of 12-lead ECG data.
