1. A system for adaptively processing patient monitoring signals, comprising:

  • an input processor configured to acquire a signal having an amplitude representing electrical activity of a patient heart over time;

    a signal processor configured to identify different portions of said signal, where each of the different portions is associated with a respective phase of cardiac activity, by;

    inverting said signal to provide an inverted signal;

    aligning said signal and said inverted signal based on their respective amplitudes during a cardiac rest portion; and

    identifying one or more of the different portions of said signal based on one or more intersections point of said aligned signal and inverted signal; and

    a plurality of adaptive signal filters, each of the plurality of adaptive signal filters configured to filter a respective plurality of bandwidths of a respective one of the different portions of said signal.
