Patent ID: 8891713

Claim:
A patient medical signal processing system for adaptively reconstructing a cardiac signal sampled using a varying sampling rate, comprising: an input processor for receiving, first data representing a first portion of a cardiac signal derived by sampling at a first sampling rate and second data representing a second portion of said cardiac signal derived by sampling at a second sampling rate, said first and said second sampling rates being different and comprising a master clock rate or an integer division of said master clock rate; and a signal processor for providing a reconstructed sampled cardiac signal by, interpolating said second data to provide third data at said first sampling rate, providing at least two different specific filters for respective different frequency bands of said third data, adaptively adjusting, in response to feedback, one or more parameters of at least one of the different specific filters to decrease corresponding specific noise, and combining said first data and said third data to provide said reconstructed sampled cardiac signal.
