    Heart disease is the largest cause of death in the western world. Modelling cardiac tissue is of clear importance to investigating the electrical activity of the heart. This electrical activity is difficult to investigate directly due to the enclosed nature of the heart. This project aims to provide an accurate representation of cardiac tissue using a cellular automaton. Previous approaches of cellular automaton models of excitable media are reviewed and critically analysed. Then a model is developed which investigates the generation of isotropic waves in an efficient method. The developed model is then specialised to reflect the characteristics found in cardiac tissue. Firstly the electrical activity of heart tissue is matched. An approach is then described to introduce the restitution property to the model. This property is validated by matching cardiac restitution curves from literature. Finally cellular automaton models are implemented on a parallel processor to provide a possible performance increase. Finally a conclusion is provided evaluating the successes and failures of the project including ideas for future development.
