Abstract

The purpose of this study is to develop and test a mathematical method to reconstruct endocardial potentials from cavity potential data measured with a small multielectrode intracavitary probe. Such a method will enhance the diagnostic capability of electrophysiologic studies and the ability to locate the site of origin of arrhythmias. Boundary element method, combined with Tikkonov regularization. was developed and tested on an idealized model of the probe-heart-torso volume conductor. The inverse solution restored stability and accuracy to the endocardial potentials in the presence of errors in estimating cavity geometry and probe position. Experimental testing in an isolated canine heart preparation is in progress.
