comparison of macroscopic models of excitation and force propagation in the heart computer aided simulations of the heart provide knowledge of phenomena which are commonly neither visible nor measurable with current techniques this knowledge can be applied eg in cardiologic diagnosis and therapy a variety of models was created to reconstruct cardiac processes eg electrical propagation and force development in this work different macroscopic models were compared ie models based on excitationdiffusion equations and cellular automata the comparison was carried out concerning reconstructability of cardiac phenomena mathematical and biophysical foundation as well as computational expense particularly the reconstructability of electromechanic feedback mechanisms was examined perspectives for further developments and improvements of models were given
