Abstract
Methods and systems are provided for determination and mapping of vector fields which characterize wavefront motion through space and time. The inventive methods and systems utilize data from spatially-distributed locations and maps wavefront vector flow fields in an entirely automated manner. These maps can be used to characterize the activation as planar, centrifugal, or rotational. Further, the strength of rotation or divergence is determined from these fields and can be used to select spatial points of significantly increased rotational or focal activity. As applied to electrophysiological data recorded during heart rhythm disorders in patients, the inventive method provides a means of visual interpretation of complex activation maps. The information related to the strength and location of rotation and centrifugal activity during episodes of arrhythmia can guide therapies designed to treat such disorders.
