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
