Ecg Data Detection And Processing System Analysis And Design

The software of the cardio-data disposal and inspection aims at quickly displaying and analysing cardio-data in order to help doctor diagnose cardiopathy. This thesis introduces Object_Oriented programming thoughts', design methods and theories of cardio-vvave analyse and cardiopathy diagnoses, which are used in the development of this software.The thesis recommends in detail how to use UML (Unified Modeling Language) to analyse the requirement of user and construct the function modules of the project by utilizing use-case diagram, interactive diagram, behavior diagram. Furthermore, this paper presents how to use Object Oriented Implement Language, Delphi5.0, to realize the functions of the software. Since it need to analyse a large number of cardio-data, the thesis suggest one kind of disposal mentality that make multithread technology work with the data structure of cyclic-queue to improve the executive efficiency of software. At last, the article focus on theories about using the arithmetic of equivalence difference to detect R wave, the arithmetic of window identification to detect QRS wave and the arithmetic of template comparison to detect cardiopathy.By using above-mentioned technologies and methods, software can have the functions of cardio-wave display, characteristic wave location, cardiopathy diagnoses and so on. Thus the software has the strong practicability and has applied into practice application.
