摘要
介绍一种基于虚拟仪器LabVIEW的心电信号检测处理系统,阐明了虚拟仪器的基本概念及其在医学测量系统的应用,具体给出了心电信号放大、隔离电路的设计方案,借助数据采集DAQ卡PCI6070E实现对心电信号进行采集,通过图形化语言的编程对采集的心电数据进行分析、存储、共享。该系统可实现心电生理信号实时采集显示、心电信号HRV分析等功能,构造一套比较实用的心电虚拟仪器,对虚拟仪器在医学生物信号处理和医疗仪器开发方面有一定的参考价值。
A system of detection for ECG signal based on virtual instrument and LabVIEW is introduced. The conception of virtual instrument and its usage in medical measurement system are introduced. ECG amplifier,Data Acquisition （ DAQ ） and the data procession software are advanced. The system has the function of real -time displaying the ECG,data acquisition and Heart Rate Variability （HRV） analysis. It is a practical ECG vital instrument,which has the value for the research and application of vital instrument in medical equipments.
