Abstract (en)
[origin: FR2821460A1] The invention concerns a method for filtering a RR series obtained after sampling an analog cardiac signal characterising the cardiac rhythm, and which consists of a plurality of samples (RRi) defining respectively the time intervals between two successive heart beats. The method consists in detecting and automatically filtering in the series (RR) the erroneous sample(s), and to detect whether a sample (RRi) is erroneous, the value of said sample (RRi) of the series is compared with at least a self-adaptive threshold which is calculated from (N) samples of the series (RR) in a sliding window. In particular, a self-adaptive detection threshold is calculated from the mean and the standard deviation ( sigma ) of the N samples in a sliding window.
