Paper Abstract

One aspect of smooth muscle electrical activity interpretation concerns the topographical estimation of the regions of the observed features.The quantities measured correspond to differences in potential between points of the muscle.These potentials are due to the activity of some distribution of sources(pacemakers)with timevarying amplitudes and locations.A three-dimensional model is introduced to describe the basic anatomical structure of CI tract and the conduction characteristics especially locations of pacemakers and their stability.Using FEM,the spatial distribution of time-varying current density is presented.Moreover,displaying the migration of pacemaker location simplifies the interpretation of pathways of conduction and functional behaviour of CI tract under different modes of stimulation.
