Patent ID: 8103065

Claim:
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.
