Abstract
This paper presents a mathematical model of the electric field generat ed and resistance measured by a conductance catheter within a three-co mpartment ellipsoidal approximation of a cardiac ventricle. The model is based on a novel combination of analytical and numerical techniques . The numerical component of the model predicts displacement of the ca theter along the central longitudinal ventricular axis, as well as ecc entric positions off that axis. The analytical component of the model enables interactive definition of model parameters during simulation. This versatile combination enables performance of validation studies t hat include simulations of various catheter movements within a ventric le of changing geometry. The results of our simulation studies agree w ith the results of previous investigators studying ex-vivo systems.
