Abstract/OtherAbstract:
|
The problem of reconstructing the pattern of heart excitation from body surface potentials is simulated. The problem is well known as the inverse problem of electrocardiography and in a general case this problem has a non-unique solution. The relationship of the problem with the inverse problem of potential theory is shown. From this relationship a new excitation propagation model for the heart ventricles is developed. The model is based on a classical multidipole cardiogenerator, but is stable, flexible, and provides a unique solution for the inverse problem of electrocardiography. |
