Abstract

The invention relates to an apparatus (100, 200) for performing pulse wave velocity measurements of blood flowing through a blood vessel, comprising at least a first and a second pulse detector, first selecting means (106) for selecting one of the first and the second detectors (104) and an amplifier (108) for amplifying a signal provided by the selected one of the first (102) and second (104) detectors.
