Abstract
A pulse wave detecting apparatus including a sensing device sensing a pulse wave produced from an arterial vessel of a subject, a storing device concurrently storing the pulse wave signals generated by pressure sensing elements of the sensing device, a selecting device selecting, as an optimum pressure sensing element, one of the pressure sensing elements such that an amplitude of the pulse wave signal from the selected one element is the greatest of the amplitudes of the pulse wave signals stored in the storing means, a judging device judging whether or not the pulse wave signal from the selected one element is abnormal, and a changing device which, if an affirmative judgement is provided by the judging device, changes the optimum pressure sensing element from the selected one element to another of the pressure sensing elements such that an amplitude of the pulse wave signal from the selected another element is the greatest of the amplitudes of the pulse wave signals which are stored in the storing device concurrently with the abnormal pulse wave signal.
