Implanted Electrodes Potential Distribution In A Man Model

The finite element (FE) method has been used to analyze and determine the p otential distribution produced by implanted stimulating electrodes used in conjunction with an implanted defibrillator. These electrodes are used to deliver an energy shock to halt ventricular fibrillation during fatal arrhythmias in human beings. The (FE) solution was obtained by solving the Laplace equation based on a Galerkin Procedure. An infinite cylindrical model, having three c oaxial layers of tissue with two electrodes, was used to show preliminary results of the (FE) Model. An analytical procedure was developed and used to validate the (FE) results.
