Abstract We present a new approach to cardiovascular analysis based on a well-known signal processing technique, namely, the frequency subband decomposition. The subbands are chosen in accordance with physiological standards: (1) 0–0.04 Hz, (2) 0.04–0.15 Hz, (3) 0.15–0.4 Hz. It is shown that such a pre-processing drastically improves the accuracy of the analysis and introduces a new direction in the understanding of the relationships between cardiovascular signals. © 1998 Biomedical Engineering Society.
