Estimation of endocardial geometry and myocardial conductivity from catheter impedance measurements


Conference Paper

An impedance catheter volume measurement system was modeled in spherical and spheroidal configurations to see if geometric and conductivity parameters could be estimated from measured potentials. Good results were obtained in both noise free and noise added signal cases for the sphere estimating radius and conductivity. However, in the spheroidal case sufficient estimates could be obtained in the noiseless case for major and minor axes and conductivity, but in the added noise case the results were poor.
