摘要
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.
