Abstract
An implantable cardiac device is provided. The implantable cardiac device includes a sensing unit adapted to measure an intrathoracic or intracardiac impedance, pressure, and/or accelerometry input stream, which includes a patient's respiratory waveforms. Furthermore, the implantable cardiac device includes a quantizer-unit adapted to sample the input stream with an initial sampling frequency Fs, providing input samples of the input stream. The implantable cardiac device further includes a filter banksuited to perform a streaming Wavelet transformation on the input samples on a sample-by-sample basis, using the initial sampling frequency Fs provided by the quantizer-unit, wherein the streaming Wavelet transformation is adapted to perform a source separation, extracting, and separating the respiratory waveforms of the input stream.
