An improved numerical method for strong coupling of excitation and contraction models in the heart

This paper was one of the first to analyse the numerical stability of the equations for modelling coupled electromechanics in the heart. This study initiated further numerical, clinical and physiological studies within our own group. The work has had a significant impact internationally and has been referenced, implemented, developed and analysed by groups in San Diego, Oxford, Auckland, Belgium, Austria and Norway. The proposed technique reduced computation time for a heartbeat from 3-weeks to 2-days, fundamentally altering the scope of questions that could be investigated using cardiac electromechanics simulations in both clinical and physiological contexts.
