Journal ArticleDOI
An Efficient Algorithm for Spectral Analysis of Heart Rate Variability
TL;DR: It is demonstrated that the amplitude spectrum of this heart rate signal more closely matches that of the input signal to an integral pulse frequency modulation model of the heart's pacemaker than do the spectra of other ECG-derived heart rate signals.
Journal ArticleDOI
Transfer function analysis of the circulation: unique insights into cardiovascular regulation.
TL;DR: The transfer functions between respiration, heart rate (HR), and phasic, systolic, diastolic, and pulse arterial pressures in 14 healthy subjects during 6-min periods in which the respiratory rate was controlled in a predetermined but erratic fashion are determined.
Journal ArticleDOI
Assessment of autonomic regulation in chronic congestive heart failure by heart rate spectral analysis.

TL;DR: The frequency characteristics of HR fluctuations in patients with severe CHF are consistent with abnormal baroreflex responsiveness to physiologic stimuli, and suggest that there is diminished vagal, but relatively preserved sympathetic, modulation of HR.
Journal ArticleDOI
Beat to beat variability in cardiovascular variables: noise or music?
TL;DR: This method promises to provide a new approach to the clinical diagnosis and management of alterations in cardiovascular regulation and stability.
Journal ArticleDOI
Transfer function analysis of autonomic regulation. I. Canine atrial rate response.
TL;DR: The approach entails the imposition of a signal with broad frequency content as an input excitation and the computation of a system transfer function using spectral estimation techniques and it is found that the sinoatrial node responds as a low-pass filter to fluctuations in either sympathetic or parasympathetic tone.
