An apparatus (1) including a pulse wave sensor (3), or first and second pulse wave sensors (3, 30), and a processing and calculation unit (5) configured to: determine the moment that a pulse wave reaches a finger of a hand of the subject when said (3) or one of said sensor (s) (3, 30) is positioned on said finger; determine the moment that a pulse wave reaches a toe of the subject when said (3) or one of said sensor (s) (3, 30) is positioned on said toe; calculate a time value, the so-called "aortic transit time", as a function of the difference between said moments; and calculate a speed, the so-called "aortic pulse wave speed", as a function of said aortic transit time, said calculation including dividing a value, the so-called "aortic length (Laort)", as a function of the height (H) and age of the subject by said aortic transit time (Top_aort). The corresponding method is also described. |
