Abstract :
A Holter system is designed based on MSP430 and LPC2292 dual-core. Real-time ECG data acquisition, full-color LCD control, and data storage in SD memory card are accomplished. Additionally, real-time ECG data analysis algorithm is realized to detect QRS and premature ventricular contraction (PVC). The hardware system includes ECG signal preamplifier module, MSP430, ARM7, SD data storage module, and LCD module. The software system is base on UCOSII, UCGUI, and FAT16 FS, to improve system operability. Low power design is achieved by MSP430F1611 and power-down mode of LPC2292, so that battery-powered is fulfilled even for 48 hours.
