    摘要: A method includes receiving, in a processor, a two-dimensional (2D) electroanatomical (EA) map of an interior surface of at least a portion of a cavity of an organ of a patient, the 2D EA map including electrophysiological (EP) values measured at respective locations on the interior surface. A complex analytic function is fitted to a set of the EP values that were measured in a given region of the 2D EA map. A singularity is identified in the fitted complex analytic function. The region is projected onto a three-dimensional (3D) EA map of the interior surface. At least part of the 3D EA map is presented to a user, including indicating an arrhythmogenic EP activity at a location on the 3D EA map corresponding to the singularity identified in the fitted complex analytic function.
