An ECG 7-Lead Monitoring System Designing Based On Lower-Power

摘要

Electrocardiograph (ECG) 7-lead monitoring system is designed in this paper. The proposed presents some improvements in hardware design. Firstly, A-two-stage amplifier circuit is designed in this scheme to get a good analog ECG signal. Secondly, the MCU selects a low-power chip-MSP430F149. Lastly, in order to avoid electromagnetic interference (EMI), we put the electromagnetic compatibility (EMC) into consideration in the circuit component selection and printed circuit board layout. The system converts the three-way signal from the hardware circuit into a seven-way signal.
