Abstract
The deformation of myocard takes a vital part in the pumping function of the heart muscle. Knowledge of myocard anatomy and physiology makes it possible to create models of cardiac behavior. These models can be used for surgery planning, educational and research purposes. Simulations can be performed, which are beyond the capability of physical experiments. Volume models of myocard are necessary for realistic simulations. The deformation model presented in this work is based on a mass spring system parameterized by a continuum mechanics deformation model. Electrophysiology and excitation propagation of myocard were simulated and the resulting force development was used as input for the deformation models. Electromechanical coupled simulations with simple myocard geometries were carried out to show the capability of the deformation model in reconstruction of cardiac deformation.
