application of contemporary measurement and analysis techniques to human cardiovascular system
Contemporary computer based measurement and analysis techniques enable noninvasive observations of several cardiovascular functions and their analysis in time, frequency and phase space domain. Time-frequency analysis of signals, derived from respiration, cardiac function and blood flow revealed the existence of five almost periodic frequency components on time scale of minutes. These systems are mutually dependent via couplings. Their strength plays essentinal role in the performance of the system, thus pointing to practical applications in diagnosis and prediction of cardiovascular functions.
