Combining to a singularity plural-anatomical-site, heart-functionality measurements
First Claim
1. An electroacoustic, cardiographic, computer-implemented method for combining, to a singularity from a plurality of anatomical source sites, heart-functionality parameter measurements comprisingover a predetermined number of cardiac cycles, collecting ECG and heart-sound data, including plural-anatomical-site heart-sound data,computer processing such collected data to acquire per-site, per-cycle nominal values for the selected parameter,relative to each site, computing the arithmetic mean of the nominal selected-parameter values associated with that site by summing all of such site-associated nominal values and dividing the sum by the predetermined number of cycles,also relative to each site, computing the variance of the associated nominal values by summing the squared difference between each such nominal value and the computed arithmetic mean, and dividing this squared-difference sum by the predetermined number of cycles,computing weighted values for all of the nominal values that are associated with all of the plural anatomical sites by multiplying each such per-site value by a weight coefficient which is equal to the inverse of the variance that is associated with the value'"'"'s associated anatomical site,computing the weighted average of all of the nominal values that are associated with all of the plural anatomical sites by summing all of the weighted values and then dividing that weighted-value sum by the sum of all of the weight coefficients, andpresenting the computed weighted average as being the assessed, combined, singular value of the selected heart-functionality parameter.

Abstract
Combining, to a singularity, from a plurality of anatomical sites, and over a plurality of heart cycles a collection of selected heart-functionality parameter measurements, such as EMAT, LVST, PADT, and AAFT measurements, including (a) collecting ECG and heart-sound data from plural anatomical sites, (b) computer processing such data to acquire plural, per-site, per-heart-cycle, nominal values for the selected parameter, (c) utilizing arithmetic mean and selected variance calculations related to such nominal values processing, and determined weight coefficients, computing weighted nominal values, (d) computing a weighted, nominal-value average of all of the nominal values by summing all of the weighted values and dividing that sum by the sum of all of the weight coefficients, and (e) presenting the computed weighted average as the combined, singularity value of the selected heart-functionality parameter.
