基于虚拟仪器的远程心电监护系统的研制

Research on ECG Telemonitoring System Based on Virtual Instrument

目的:研制一种远程心电监护系统,满足众多心脏病患者在医院之外享受医疗保健的愿望。方法:采用ECG105单通道心电板采集心电信号,并进行相应的预处理;通过串口将心电数据传入计算机,充分利用计算机强大的信号分析处理功能,采用LabVIEW平台研制出基于虚拟仪器的远程心电监护系统。结果:在实时显示心电波形的同时,可对已保存的心电记录进行回放和分析,可对心率是否异常进行判断和报警,并可实现心电数据的远程传输。结论:方便地实现了心电信号的显示、存储、回放、诊断分析以及远程通信,系统将大部分需要由传统硬件检测电路来完成的功能改由软件来实现,便于今后的功能扩展。强大的功能及低成本为众多心脏病患者提供了方便。

Objective To develop an ECG telemonitoring system which can meet many needs of cardiopaths with enjoying medical care out of hospitals. Methods The signals of collection and pretreatment in ECG105 that were transmitted to the computer through serial port, the computer＇s powerful functions in analyzing and processing signal were utilized fully to design ECG telemonitoring system based on virtual instrument by LabVIEW. Results The system can redisplay and analyze the stored signal and judge whether the heart rate is abnormal, and implement ECG data remote transmission. Conclusion The display, storage, redisplay, diagnosis and tekeeommunications of ECG can be achieved conveniently and provide convenience for many cardiopaths with its powerful functions and low cost.
