Possible Four-Electrode Configurations for Measuring Cardiac Tissue Fiber Rotation
MetadataShow full item record
Anumber of electrode configurations, based on the usual fourelectrode probe, are analysed in relation to the effect that changes in cardiac fiber rotation have on the potentials measured. Simulations are carried out using amathematical model and a new solution technique, based on Fourier series followed by a simple one-dimensional finite difference scheme. This electrode analysis leads to the proposal of an in-principle method for determining cardiac fiber rotation.
