Method and system for providing characterizations of waveform representations of heart function

摘要

A method and system for providing highly accurate characterizations of waveform representations of heart function, such as QRS complexes, where such waveform representations are derived from electrocardiographic measurements. The method and system accomplish their objects via the following. One or more signals indicative of heart function are measured and sampled. One or more signal quality indexes are calculated for each of the measured and sampled one or more signals. The signal quality indexes are calculated by dividing a maximum sample value for each one or more measured and sampled signal by a calculated divisor. One or more weighting factors, dependent upon the calculated signal quality index of each of the one or more measured and sampled signals are calculated. And, a waveform representation composed of each of the one or more measured and sampled signals indicative of heart function multiplied by its calculated weighting factor is created.
