摘要
目的:研制使用SD卡作为存储介质的动态心电系统。方法:使用MSP430F449单片机采集3通道的心电信号,通过同步通讯接口,记录在SD卡上,在计算机上进行数据的回放和分析。结果:构建了基于SD卡的便携式动态心电系统。使用SD卡,可以提高动态心电系统的存储能力。结论:提供了一个低成本、高性能的动态心电系统的解决方案。
Objective To develop ECG Hoher system with SD card as storage medium. Methods Data that used MSP430F449 SCM to acquire 3-channel ECG signal to record SD card through serial peripheral interface were reviewed and analyzed on computer. Results Portable ECG Holter System based on SD card is realized. The using of SD card can enhance storage performance. Conclusion Low-cost, and high-performance solution program is observed.
