Claim One:
1. A system configured to detect a location of a source of at least one cardiac rhythm disorder in a patient's heart, comprising: at least one computing device comprising at least one non-transitory computer readable medium configured to store instructions executable by at least one processor to determine the source and location of the cardiac rhythm disorder in the patient's heart, the computing device being configured to: (a) receive electrogram signals; (b) normalize or adjust amplitudes of the electrogram signals; (c) assign predetermined positions of the electrodes on a mapping electrode assembly employed to acquire the electrogram signals to their corresponding electrogram signals; (c) provide or generate a two-dimensional (2D) spatial map of the electrode positions; (d) for each or selected discrete times over which the electrogram signals are being processed, process the amplitude-adjusted electrogram signals to generate a plurality of three-dimensional electrogram surfaces corresponding at least partially to the 2D map, one surface being generated for each such time, and (e) process the plurality of three-dimensional electrogram surfaces through time to generate a velocity vector map corresponding at least partially to the 2D map, the velocity vector map being configured to reveal the location of the source of the at least one cardiac rhythm disorder.
