The invention relates to a device for processing intracardiac signals, which comprises a memory unit (4) arranged to receive electrocardiogram data and synchronised electrogram data, a detector (6) arranged to analyse the electrocardiogram data and to detect QRS wave instants therein, an analyser (8) arranged to perform a wavelet transform of the electrogram data, an extractor (10) arranged to collect coefficients from the wavelet transform, each associated with a QRS wave instant detected by the detector (6), and to store them in a buffer (14), and a composer (12) arranged to extract a QRS fingerprint signal from the buffer (14) and subtract it from the wavelet transform at the QRS wave instants, and to output denoised electrogram data by inverse wavelet transform of the resulting signal.
An intracardiac signal processing device, comprising a memory arranged to receive electrocardiogram data and synchronised electrogram data, a detector arranged to analyse the electrocardiogram data and to detect therein QRS wave time points, an analyser arranged to carry out a wavelet transform of the electrogram data, an extractor arranged to derive in the wavelet transform coefficients each associated with a QRS wave time point detected by the detector, and to store them in a buffer, and a composer arranged to extract from the buffer a QRS fingerprint signal and subtract it in the wavelet transform at the QRS wave time points, and to produce as output denoised electrogram data by inverse wavelet transform of the resulting signal.
