Printed Circuit Board Design of ECM of Multi-lead ECG Monitoring System

本文对多导联心电监护系统从印制电路板(PCB)的器件布局、布线等方面来进行了电磁兼容性研究和设计,设计完成的多导联心电监护系统能够获得实时的性能良好的心电信号。在日常生活环境下,对所设计的心电信号系统进行了实时监护测试,电路板在裸露状态下可以检测到稳定的心电信号。此测试结果表明该系统具有良好的电磁兼容性和实际应用意义。

In this paper, the multi-lead ECG monitoring system of ECM is researched and analyzed from the perspectives of printed circuit board(PCB) component layout and wiring. And the finished system can get a good real-time performance of ECG signal. Under the environment in daily life, through the real-time monitoring test of the designed ECG system, the PCB in the bare state can detect stable ECG signal. The test results show that the system has a good electromagnetic compatibility and practical application.
