First Claim
Patent Images
1. A method for characterizing ST segment (STS) variations of a patient, comprising:
- collecting and storing STS variations for multiple data collection periods, each of the data collection periods separated by a cycle;
calculating multiple statistical parameters based on the STS variations collected, wherein each statistical parameter is associated with a corresponding data collection period;
sorting the calculated statistical parameters for the STS variations into a plurality of heart rate bins based on at least two or more of a normal resting heart rate bin, a normal active heart rate bin, an elevated heart rate bin, a fast heart rate bin, an arrhythmic heart rate bin, and a bradycardia heart rate bin for each of the multiple data collection periods; and
constructing a STS variation trend of the sorted STS variations as a function of the sorted heart rate bins for each of the multiple data collection periods.

Abstract
A system and method are provided for characterizing ST segment (STS) variations of a patient. The method includes collecting STS variations for multiple data collection periods, calculating multiple statistical parameters based on the collected STS variations, and constructing a STS variation trend. The statistical parameters are associated with a corresponding data collection period. The STS variation trend is based on the multiple statistical parameters over multiple data collection periods.
