Abstract(in English) | In this research, we shall estimate the electric dipole dynamics by means of an inverse estimation scheme with respect to the spatio-temporal patterns of the activity in the human heart dynamics. The Finite Element Method (FEM) is utilized to evaluate the potential field in vivo according to the measured surface potentials comparing with those which are generated from the predicted electric dipole. Therein the dipole location concerned with the surface potential as well as the measured one is to be successively computed by means of the Genetic Algorithm (GA). The experimental results imply that the senses of the estimated dipole location and rotation are found to be clockwise and counterclockwise, respectively. In addition on the basis of the Lyapunov analysis the coordinate of the dipole is found to result in chaotic behavior. |
