METHOD AND DEVICE FOR FILTERING A SERIES RR OBTAINED FROM A CARDIAC SIGNAL WITH AUTOMATIC CONTROL OF THE QUALITY OF THE RR SERIES

摘要

The method allows the filtering of an initial RR series consisting of a plurality of samples (RRi) which are respectively a function of the time intervals (δti) which separate two successive heart beats. To perform this filtering, one automatically detects in the initial RR series if one or more successive samples (RRi) are erroneous, and one or the samples (RRi) detected as being erroneous are automatically corrected in the series RR by replacing them with one or more several reconstructed samples (RRc), so as to obtain a series RR if necessary partially reconstructed, and possibly one resamples the series RR, so as to obtain a series RR, if necessary partially reconstructed, and resampled . The quality of the RR series is automatically controlled by counting in a predefined sliding window the number (NbPertub) of RR samples (RRc) that have been reconstructed and / or, if applicable, the number (NbPertub) of samples ( RRrc) of the RR series that have been reconstructed and resampled.
