Method and system for trending variation in coronary burden across multiple heart rate ranges
First Claim
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.

Abstract
A method and system are provided for trending variation in coronary burden across multiple heart rate ranges. The method and system include obtaining cardiac signals having a segment of interest over a period of time where each cardiac signal has an associated heart rate that falls within at least one heart rate range. Segment variations of the segment of interest are determined and grouped based on the associated heart rates to produce distributions of segment variations that are associated with the heart rate ranges. Trending information is produced by automatically comparing the distributions of segment variations between different heart rate ranges.

15. A system for trending variation in coronary burden across multiple heart rate ranges, comprising:
-
an input for 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; a processor for determining segment variations of the segment of interest within the cardiac signals, the processor for each collection time period, grouping the segment variations, for each collection time period, 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 for each collection time period, each of the distributions being uniquely associated with one of the heart rate ranges; and memory storing the sets of distributions, within each set of distributions, the processor comparing the distributions of segment variations within each set of distributions, to produce trending information that represents a relation between the distributions within the corresponding set of distributions and for the corresponding collection time period, the memory storing the trending information for the multiple collection time periods over the trending period of time. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
