1. A method for analysing pressure-signals derivable from pressure measurements on or in a body of a human being or animal, comprising sampling said signals at specific intervals, converting the pressure signals into pressure-related digital data with a time reference,identifying from said digital data features related to single pressure waves in said pressure signals,said identifying step including determination of a minimum pressure value related to diastolic minimum value and a maximum pressure value related to systolic maximum value, anddetermining at least one parameter of the single wave parameters elected from the group of:

  • pressure amplitude=Δ

    P=[(maximum pressure value)−

    (minimum pressure value)], latency (Δ

    T), rise time or rise time coefficient=Δ

    P/Δ

    T, and wavelength of the single wave, anddetermining numbers of said single pressure waves occurring during a given time sequence,wherein said determining of numbers includes;

    determining numbers of single pressure waves with pre-selected values of one or more of said single pressure wave parameters during said given time sequence, andfurther includes determining numbers of single pressure waves with pre-selected combinations of two or more of said single pressure wave parameters during said given time sequence.
