The property of cardiac tissue at a local site, a plurality of sites or in a region of a heart may be characterized based on local electrograms measured at the local site, at a plurality of sites or in the region, respectively. The property may be characterized by normalizing the local electrogram, extracting a feature vector from the normalized electrogram, and classifying the tissue property based on the feature vector. The method of the invention may further comprise computing a map of the tissue property and treating the tissue based on the resultant map. Apparatus to characterize the property includes a catheter and a processor to normalize the local electrogram, extract the feature vector from the electrogram and classify the tissue based on the feature vector.
