1. A method of analyzing cardiac electrophysiological signals, the method comprising the activities of:

  • acquiring a set of signal data representing a plurality of cardiac electrophysiological signals as a function of time;

    identifying individual signals within the set of acquired signal data, an individual signal comprising data values representing a plurality of sample points from a single heartbeat;

    selecting one of the identified individual signals or a derived signal representing an average of a subset of the identified individual signals as an analysis signal;

    identifying data representing a reference signal, the reference signal comprising data values representing a plurality of sample points;

    aligning the sample points of the reference signal with the sample points of the analysis signal;

    calculating a single value representative of differences between the sample points of the reference signal and the corresponding sample points of the analysis signal; and

    communicating data indicating a calculated value to a destination for viewing by a user.
