A patient medical signal processing system adaptively reconstructs a medical signal sampled using a varying sampling rate. The system includes an input processor and a signal processor. The input processor receives first data and second data. The first data represents a first portion of a medical signal derived by sampling at a first sampling rate and the second data represents a second portion of the medical signal derived by sampling at a second sampling rate. The first and the second sampling rates are different and comprise a master clock rate or an integer division of the master clock rate. A signal processor provides a reconstructed sampled medical signal by, interpolating the second data to provide third data at the first sampling rate and combining the first data and the third data to provide the reconstructed sampled medical signal.
