Abstract: The method allows controlling the quality of an initial RR series made up of a plurality of (RRi) samples which are respectively a function of time intervals (?ti) which separate two successive heartbeats. During this method, one resamples the RR series so as to obtain a resampled RR series, and one automatically controls the quality of the RR series by automatically calculating at least the mathematical norm value (NORME), in a sliding window, of the resampled RR series, said mathematical norm value being given by the following formula: NORME = ? i = 1 N ? ( RR i - 1 N ? ? i = 1 N ? ( RR i ) ) 2 where N is the number of RRi samples in said window.

Abstract: The method is used for filtering an initial RR series of a plurality of (RRi) samples which are respectively a function of the time intervals (?ti) that separate two successive heartbeats. In order to carry out this filtering, one must automatically detect in the initial RR series if one or more successive (RRi) samples are incorrect, and automatically correct in the RR series one or more of the (RRi) samples detected as being incorrect by replacing them with one or more reconstructed (RRc) samples so as to obtain an RR series. One must automatically control the quality of the RR series by counting, in a predefined sliding window, the number (NbPertub) of (RRc) samples of the RR series that were reconstructed, and/or, if applicable, the number (NbPertub) of (RRrc) samples of the RR series that were reconstructed and resampled.

Abstract: A method for measuring a physiological parameter, such as a biological rhythm, on the basis of at least two sensors, and to an associated measurement device. The method includes the following steps of: measuring the physiological parameter for each sensor, allowing the generation of a series of measurements of at least two values; evaluating the level of consistency of each value from the measurement series; selecting a value from the set of values in the series as a function of the corresponding level of consistency and a so-called reference value, in order to determine a new reference value; and storing the new reference value.

Abstract: The inventive method for processing an RR series comprises a plurality of (RR) samples representing time intervals (dti) between two successive heart beats or the inverse (1/dti) of said time intervals consists in selecting (N) (RRi) samples in a main time window having a predetermined length (n), in cutting said main window into (m) subwindows (Fj), in calculating an intermediate parameter (A1) for each subwindow (Fj) on the basis of the (RRi) samples contained in the subwindow (Fj) and in calculating a final parameter as a function of the intermediate parameters (Aj). The invention is used for analysing a cardiac rhythm variability, in particular for assessing a patient's pain or stress.

Abstract: The RR series, comprising a number of samples respectively defining the time interval between two successive heartbeats, is filtered by means of a digital band-pass filter (Fk), having a given band-pass [fc; f?c] and preferably by means of a recursive elective filter (RII). A variability index (Ik), is calculated which is a function of the instantaneous amplitude [vs(n)] of the discrete signal (Sk) coming from said band-pass filter. The variability index (Ik) is preferably a function of and particularly equal to the effective value of the discrete signal (Sk) from the band-pass filter.
