Abstract :
This paper outlines an efficient computational procedure for solving electrocardiographic problems. It is applied here to modelling the electrical activity from the heart to the body surface. The model uses a combined finite element/boundary element method involving cubic Hermite basis functions. The model geometry used here is obtained by fitting to data points measured from magnetic resonance images (MRI) using a nonlinear fitting procedure. The accuracy and efficiency of this new procedure is illustrated with two examples
