1. In an electronic sphygmomanometer, the combination comprising:

  • means for providing, from a first source, detected korotkoff sounds as electrical signals;

    means for providing, from a second source, associated pressure waveform korotkoff sound precursors as electrical signals, each of said korotkoff sound precursors relating solely to the indivdidual korotkoff sound signal with which that precursor is associated; and

    analyzing means for analyzing the waveforms of all of said electrical signals to determine their conformity with predetermined waveform characteristics, whereby those electrical signals having waveforms representative of true korotkoff sounds are separated from those electrical signals which do not represent true korotkoff sounds.
