New signal processing techniques for improved reliability of impedance cardiography
Different techniques have been developed for parameter extraction and segmentation of the impedance cardiogram for improved reliability and precision of beat-to-beat determination of systolic time intervals, stroke volume, and related cardiac indices. The solutions presented improve on previous techniques by: (1) substantially reducing jitter in the localization of events within the cardiac cycle; (2) providing exact determination of signal amplitudes even in the presence of artifacts and interference signals; and (3) eliminating the influence of respiratory signal modulation on parameter extraction.<>
