1. A method for trending variation in coronary burden across multiple heart rate ranges, comprising:

  • obtaining cardiac signals over multiple collection time periods within a trending period of time, each cardiac signal having an associated heart rate falling within at least one of the heart rate ranges, each cardiac signal having a segment of interest;

    determining segment variations of the segment of interest within the cardiac signals;

    for each collection time period, grouping the segment variations based on the associated heart rates of the cardiac signals from which the segment variations were determined to produce a set of distributions of segment variations, each of the distributions being uniquely associated with one of the heart rate ranges;

    within each set of distributions, comparing automatically the distributions of segment variations, between different heart rate ranges, to produce trending information representing a relation between the distributions within the corresponding set of distributions and for the corresponding collection time period; and

    presenting the trending information for the multiple collection time periods over the trending period of time.
