基于LabVIEW的心电信号采集系统的设计

The Design of ECG Aquiring System on LabVIEW

目的 设计一套基于LabVIEW的心电信号采集系统。方法 在插入式信号采集板DAQ的硬件支持下 ,利用LabVIEW编程软件 ,设计了一套双通道心电信号采集系统 ,本系统用传统的心电图机采集心电信号 ,经过调解后 ,输入计算机采集并显示 ,同时 ,为了能够对心电信号作进一步的研究 ,利用小波变换对心电信号进行了处理。结果 成功采集到心电信号 ,并计算了心率的大小。

Objective To design the ECG acquiring system on LabVIEW.Methods With a DAQ board, we design an ECG acquisition system based on LabVIEW. The electrocardiographic signal is conditioned by a traditional ECG machine and acquired by a DAQ board on a computer. A wavelet transformation was used to process the acquired signal.Results The ECG signals were acquired successfully and the heartbeat rate was calculated.
