1. Apparatus for analyzing measured pulse waveform and for identifying a diastolic portion of a digitized arterial blood pressure waveform comprising a computer programmed to carry out the method of:

  • analyzing diastolic portions of each of a plurality of individual beats, including;

    a) selecting a point representative of the onset of diastole;

    b) selecting a point representative of the end of diastole; and

    c) fitting a curve to the selected diastolic portions; and

    , determining resultant values as a weighted average of the values from the analysis of the analyzed diastolic portions based on their error estimates and quality of curve fit.
