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.
