一种简易的心电过采样系统

A Simple Oversampling System for ECG Detection Based on Labview

传统的心电采集系统缺乏灵活性,模拟信号调理部分较为复杂;为解决此问题,基于DAQ采集卡和Labview图形编程软件建立心电采集系统,对模拟信号调理部分进行精简改进,并引入过采样技术;结果显示,该系统具有灵活性,调试方便,能够准确测量心电信号,且过采样技术提高了检测信号的信噪比;因此,该系统是一个方便实用的心电采集平台。

Traditional ECG detection system lacks for flexibility and analog signal conditioning circuit is complex. To resolve the problem, a new ECG detection system was developed based on DAQ card and Labview and oversampling technique was fulfilled in Labview. The signal conditioning circuit was simplified. The result indicated that the new system was flexible and easy to debug and could detect ECG signal accurately. Oversampling technique could improve the ECG signal’s signal to noise ratio. So the system is a convenient and applied ECG detection system.
