便携式十二导联低功耗心电监护系统的设计

Design of a Portable Low Power 12-lead ECG Monitoring System

设计了一个便携式十二导联低功耗心电监护系统。系统由采用硬件滤波的前端采集电路模块、信号处理模块和显示模块组成。前端采集模块对信号进行放大并通过相应的滤波电路对信号进行滤波处理,信号经过处理模块后显示在上位机。本系统具有体积小、便于携带的特点,并利用低功耗的处理芯片使得长时间的实时心电监控更加简单方便。

This paper presents a portable low power 12-lead ECG monitoring System. The system consists of the front-end acquisition circuits module with hardware filters, signal processing module and display module. The acquisition module amplifies the signals and filters the noises. The analog signals pass through the signal processing module and finally display on the computer. The system is small and convenient to carry and uses the low power chips to support a long-term monitoring.
