dc.description.abstractThe theme of this thesis is the use of the bidomain equations for modeling the electrical activity in the human heart, and the pursuit of ways to use these equations for medical applications. The first paper investigates a simplification of the actual equations themselves which may contribute to speed up the necessary computing. The second looks at their use in inverse methods to identify ischemic heart disease from electrocardiograms (ECGs) recorded at the body surface. In Paper III they are simply used to give indications of where to take measurements of the body surface potential. The bidomain equations form the conceptual basis of this work, and while the equations themselves are presented in each of the following papers, we will here go into further detail about this model and the electrical properties of the human heart in general.eng
