Application Of Embedded Technology On A Portable ECG Recorder

With the improvement of the living standard and the acceleration of the living rhythm, the heart illness is become one of main reasons which are harmful to human healthy, and the Holter is become more and more important as a operative check method to the heart illness. As we know, with the application of Embedded technology on Holter, the Dynamic Electrocardio- gram get more improvement, but it can not meet some application requires of human which is Electrocardiogram real-time dealing with and diagnosis.This paper introduces the Electrocardiogram real-time dealing with and diagnosis, and give a detail discuss on all parts of the works by a portable Holter research.Firstly, this article introduces the development of Embedded System and Dynamic Electrocardiogram. The work's situation, studying purpose, contents and configuration are discussed. Then, by analysis of Electrocardiogram, the traits of Holter is introduced, and then bring up the design idea of the work's software and hardware, and the work's design and engineering materializing are detail discussed.Secondly, on the basis of Embedded Operation System's analysis, Opera- tion System's traits are introduced in the light ofμC/OS-II's.vital parts such as task management, task communication and so on.And then, the work's Boot Loader's function and carry out andμC/OS-II's migrate are detail discussed, and aim at shortage ofμC/OS-II, the improvement is carry out on the basis of hardware which microprocessor is LPC2292.Thirdly, the work's software design and execute procedure are introduced. Then Electrocardiogram real-time dealing with and diagnosis which is autol- earning subprogram, 50 Hz filtering subprogram and analysis of wave form su-bprogram.In the end, summarizes the work of this article, discuss the achievement and shortage, and make a future sight of future research.
