Research on Software System of Portable Electrocardiogram Monitoring
Abstract: Electrocardiogram (ECG) is an approach to measurement of heart functions. In order to develop a relevant system with advanced functions and high performances, The principles, methods and primary techniques of ECG based diagnosing and/or monitoring of ECG was studied. Furthermore, a relevant software system by using a visual programming tool namely VC++ has been developed, which works with Windows OS. In this dissertation, biomedical principles of ECG based diagnosing and/or monitoring of the electrocardiogram are introduced firstly. Secondly, the functions and performances that the software system comprised are discussed along with some possible approaches to them. Finally, the corresponding software system was given in detail, with emphases on its functions, its structure and key of its implementation. The preliminary experiments show that the software system developed is basically practical in terms of its main functions and performances, and that it has some merits in preciseness of measuring, convenience of manipulating and reliability of operating. Thus, our efforts have completed basic system requirements,which comprises the software system and a USB-based data acquisition system, to become qualified for clinical applications.
