A New Multi-channel Holter Recorder

Cardiovascular disease is one of the most dangerous threats to human health. The application of dynamic electrocardiogram (DCG) is essential for the clinical diagnosis of cardiovascular disease. Therefore, it is of great significance to research high-performance dynamic electrocardiogram monitor in cardiovascular diagnose and treatment.Based on the development of one new-type holter, the ECG analysis algorithm, which is suitable for low-speed embedded system, is discussed in this thesis. The software and hardware design method of holter is proposed, with every part of design mentalities and project-realization explained in detail. The idea of setting up holter developing platform is also discussed.The research of this thesis has the following characteristics: (1) The holter developed in this thesis can sample ECG data with high accuracy, high sampling rates, and also can sample several channels simultaneously, therefore the performance has been improved greatly. (2) This holter can analyze ECG data in real-time. The algorithm adopted is suitable for the low-speed real-time embedded system. (3) Has solved two key techniques: ECG data record technology of the large capacity and low power consumption technology. (4) Has realized present popular USB bus interface, and the liquid crystal of the large screen has been used as the display interfaces of holter. (5) Has proposed the conceive of setting up the developing platform of holter.In this thesis, the development of a kind of new-type holter has been completed, and this holter has been put into practical application. This thesis also provides a good foundation for next development.
