Abstract
The problem of retrieving spiral wave parameters (frequency, radial velocity, and center location) using a minimal number (4) of spatial sensors is considered. The problem has the important application of localization of spiral wave sources of atrial fibrillation from basket catheter electrograms. Numerical simulations demonstrate that our algorithm works effectively for a wide range of parameters, and for spiral waves generated by a cellular automaton model of cardiac wave propagation.
