Abstract:
1. An electroacoustic, cardiographic, computer-implemented method for combining, to a singularity from a plurality of anatomical source sites, heart-functionality parameter measurements comprising over 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, and presenting the computed weighted average as being the assessed, combined, singular value of the selected heart-functionality parameter.
