Microcontroler based On Demand Pacemaker
Daniš, Václav ; Balogh, Jaroslav (referee) ; Sekora, Jiří (advisor)
Pacemakers have nowadays become an inseparable part of treatment in a wide range of cardiovascular diseases. The topic of this bachelors degree paper refers to and proposes the implementation of a functional type of ´On Demand´ pacemaker controlled by a microcontroller. The introductory chapters focus on a more detailed, theoretical familiarization with the complex issues of permanent heart cardiostimulation. In addition to the actual theory of pacemakers and cardiostimulation, the chapters also include those significant historical aspects in the evolution of permanent cardiostimulation, the basic structures of heart anatomy and the transmission system of the heart. Also included are the recording of heart activity and ECG analysis, both physiological and pathological. In the practical part of the paper I deal with the ´On Demand´ pacemaker controlled by a microcontroller with a firm (solid, strong, steady, fixed) repeating frequency inhibited by the R wave. Subsequently, a proposed system for its implementation is created. The next step is the creation of a scheme for the electrical connections and composition of the microcontroller programme. The final part illustrates the implementation of the model of the pacemaker itself, preceded by a verification of the efficacy of the connections in a non-solder field.
