Method for processing cardioelectric signals and corresponding device. Th e method enables processing previously sampled cardioelectric signals so as to filter the T wave, thereby improving the visualization of the P wave. The method comprises the following stages: [a] dyadic decomposition the signal into bands by calculating its wavelet transform up to a range of frequencies comprised in a first range of 15 to 150 Hz and preferably 20 to 100 Hz, [b] selection of significant bands with P wave [c] processing of the significan t bands by modifying the wavelet coefficients using statistical parametric m odels, and preferably statistical parametric noise suppression models, [d] w eighting the non-significant bands by multiplying them by a weighting functi on, and [e] reconstructing the signal. The invention also relates to a devic e for carrying out this method.
