TIME-FREQUENCY ANALYSIS OF CARDIOVASCULAR SIGNALS

H. Sorsa, V. Turjanmaa
  • Abstract:
    Cardiovascular variability signals provide information about the functioning of the autonomous nervous system and other physiological sub-systems. Signals may be measured either as continuous electrocardiogram and blood pressure signals or as so-called beat-to-beat time series of RR-intervals end e.g. systolic and diastolic blood pressure. These signals are typically nonstationary by nature, and joint time-frequency analysis can provide more information than simple time domain methods or spectral analysis. In this paper, some time-frequency methods are compared using signals measured during orthostatic tilt.
