Abstract
An electroanatomical mapping system graphically represents local activation time (LAT) information contained in data set including a plurality of electrophysiology (EP) data points. The system computes a spatial gradient over a spatial kernel centered at an EP data point and a plurality of temporal gradients for the EP data points set. Using the gradients, the electroanatomical mapping system can detect spatial outlier EP data points and temporal outlier EP data points. These outlier EP data points can then be corrected prior to outputting a graphical representation of the LAT map on a model of a cardiac surface.
