Abstract of the Disclosure Apparatus for checking pulse rate by plethysmograph detection Mrs. Jacqueline BECQUET and Mr. Hervé DENIS The invention relates to apparatus for checking pulse rate by plethysmograph detection, comprising a plethysmograph measurement device, a unit for processing the signals obtained and a display device for presenting written and/or graphic information. The technical problem posed is to eliminate as far as possible, sources of errors and, in particular, to avoid movements of the user during the measurement. According to the invention, the plethysmograph measurement device comprises two identical transducers (32) each associated with a finger of a respective hand, and the processing unit performs a correlation operation on the signals from the respective transducers to eliminate parasitic signals. The invention is particularly applicable to apparatus for use in public places.
