1. A method for electrophysiological assessment, comprising:
acquiring electrical signals from myocardial tissue at multiple locations in a chamber of a heart;
automatically deriving from the electrical signals, by a computer processor, respective annotations, which are indicative of times within a cycle of the heart at which a conduction wave in the myocardial tissue traversed the locations;
receiving an input from a user of the computer processor indicating, for a first location in the tissue where the electrical signals comprise a double-potential signal having a first annotation and a second annotation at different respective times within the cycle of the heart, a selection of the first annotation as a valid annotation;
setting a predefined distance from the first location in response to the selection of the first annotation for the first location in the tissue; wherein the predefined distance is defined by the user;
automatically identifying, by the computer processor, one or more second locations, within the predefined distance from the first location, where the electrical signals comprise double-potential signals, each having two respective annotations;
automatically selecting, by the computer processor, in response to the selection of the first annotation, one of the two respective annotations as the valid annotation at each of the one or more second locations; and
displaying the valid annotations on an electroanatomical map of the heart.
