An efficient coupled electromechanical solver for studying human re-entrant arrhythmias

The study of cardiac arrhythmias is a major focus of computational biology, and undertaking biophysically detailed simulations is computationally demanding. An efficient coupled electromechanical solver to model cardiac tissue has been developed. This provides features to model fibre direction, and utilises computationally efficient techniques to reduce the simulation times. In this paper the break up of human re-entrant arrhythmias has been simulated. The results suggest that tissue deformation is a contributory factor in the break up of stable re-entrant spiral waves.
