基于Arduino的无线心电信号采集系统设计与实现

Design and implementation of wireless ECG signal acquisition system based on Arduino

心电图是有效监测心血管疾病的无创监测方法。本文针对现有监测系统的不足,设计一套低成本、便携式、无线传输的心电信号采集系统。在开源硬件的微处理器上实时采集心电信号,并实现Pan&Tompkins检波算法对心电信号进行实时分析,将计算结果通过无线方式发给上位机。实验测试表明,该系统能有效地长时间监测受试者的心率,操作方便,成本低,在医院和家庭监测方面具有应用价值,同时,也为后续相关研究奠定了基础。

Electrocardiography is a noninvasive monitoring method for effectively monitoring cardiovascular diseases. Herein a set of low-cost and portable electrocardiogram(ECG) signal acquisition system of wireless transmission is designed to overcome the shortcomings of the existing monitoring system. Real-time ECG signals are collected on open source hardware microprocessors, and Pan & Tompkins detection algorithm is used to conduct real-time analysis of ECG signals. The obtained results are sent to the host computer via wireless transmission. The experimental tests show that the proposed system can effectively monitor the heart rate of subjects over a long period of time, with the advantages of easy operation and lower cost.The proposed system not only has application values in hospital and home monitoring, but also lays a foundation for further research.
