1. A method of measuring hemodynamic performance of a patient'"'"'s heart, comprising:

  • obtaining a template waveform representing hemodynamic performance of the heart during a first hemodynamic state;

    obtaining an autocharacterization of the template waveform;

    identifying a measure from the autocharacterization;

    obtaining a test waveform during a second hemodynamic state;

    performing a cross-characterization of the template waveform and the test waveform to obtain a cross-characterization function;

    identifying a measure from the cross-characterization function; and

    measuring a hemodynamic status of the second hemodynamic state by comparing the autocharacterization measure with the cross-characterization measure.
