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 (&#x3b4;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: where N is the number of RRi samples in said window.

Method and device for automatically checking the quality of an RR series obtained from a cardiac signal

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 (F), in calculating an intermediate parameter (A) for each subwindow (F) on the basis of the (RRi) samples contained in the subwindow (F) and in calculating a final parameter as a function of the intermediate parameters (A). The invention is used for analysing a cardiac rhythm variability, in particular for assessing a patient's pain or stress.
