1. A method for detecting a target arrhythmia in heart rhythm data with high specificity, comprising:

  • obtaining heart rhythm data generated by monitoring the activity of a heart with a medical monitoring device;

    selecting a predetermined number of contiguous heart beat intervals from the heart rhythm data as an analysis segment;

    analyzing the analysis segment to identify an irregularity in the heart beat intervals that satisfies a threshold test for arrhythmia;

    if an irregularity that satisfies the threshold test is identified, then reanalyzing the analysis segment to identify any hidden regularity in the heart beat intervals that would indicate absence of the target arrhythmia; and

    if the analysis segment was reanalyzed and no hidden regularity was identified, then designating the analysis segment as the target arrhythmia and storing the analysis segment and the designation on a non-transitory computer readable medium.
