Abstract :
The authors attempt to characterize cardiac electrical activity based on non-invasive measurements on the torso surface and knowledge of body geometry. This problem is ill-conditioned and requires regularization. The authors present a new method for estimating the regularization parameter and a new method for using both temporal and spatial constraints in the regularization simultaneously
