Abstract

The thesis deals with the methodology of controlling the pacing rate pacemakers. This thesis presents a literature search of existing management system pacemakers, which are based on defined requirements for the proposed management methodology, including sensors used to measure the necessary physical and physiological parameters. The work describes the design of their own management methodology pacing rate of the pacemaker under groundling physical activity, the influence of the autonomic nervous system and pharmacological treatment that affects heart rate. For deriving the magnitude of change in heart rate is designed fuzzy rule-based language model as a base of knowledge of on-line expert system. The function of system uses the principles of fuzzy set mathematics and fuzzy logic. Implementation of the proposed system is implemented in the Fuzzy Toolbox MATLAB environment, the simulation engine is used to verify the effectiveness of the solution. There are discussed the possibilities of the program heart rate control pacemaker in a practical system.
