1. A method for assessing a medical condition, the method comprising:

  • obtaining a first baseline template corresponding to an average of results of a first calculation performed on multiple segments of a first electrical signal acquired at a first time;

    obtaining a first captured template corresponding to an average of results of the first calculation performed on multiple segments of a second electrical signal acquired a second time later than the first time;

    obtaining a second baseline template corresponding to an average of results of a second calculation performed on multiple segments of the first electrical signal;

    obtaining a second captured template corresponding to an average of results of the second calculation performed on multiple segments of the second electrical signal;

    calculating a first variance between the first baseline and captured templates;

    calculating a second variance between the second baseline and captured templates, the first and second variances providing unequal indications of the medical condition;

    scaling the first and second variances by first and second weighting factors, respectively, to produce first and second scaled variances indicative of the relative importance of the variances; and

    calculating a first sum of the first and second scaled variances.
