1. An off-line method for analyzing cardiac electrogram data, comprising:

  • retrieving an electrogram from a memory location;

    identifying a first-channel group of candidate beats from at least a first channel of the electrogram;

    identifying a second-channel group of candidate beats from at least a second channel of an electrogram;

    for each first-channel beat candidate near a second-channel beat candidate, comparing the amplitude of the first-channel beat candidate with an amplitude of a previous beat and an amplitude of a next beat on the first electrogram channel and removing first-channel beat candidates that are outside of a first pre-determined range from either the previous or next beat; and

    for each first-channel beat candidate near a second-channel beat candidate, comparing the amplitude of the first-channel beat candidate with an amplitude of a previous beat candidate and an amplitude of a next beat candidate on the first electrogram channel and removing first-channel beat candidates that are outside of a second pre-determined range from either the previous or next beat candidate;

    wherein a first-channel beat candidate is near a second-channel beat candidate if it occurs within a first time interval from the second-channel beat candidate.
