A model is developed to describe and quantitate the error in RR interval measurement due
to the finite sampling frequency. The measured RR interval is modeled as the sum of the true …

The paper presents an alternative to Fourier techniques for assessment of heart rate
variation. The system operates on RR interval data (intervals between successive R-waves …

A definition of heart-rate variability (hrv) is given. The use of hrv measurement in both clinical
applications and the neural cardiovascular research is discussed. For the latter applications …

We present a systematic approach for detecting nonlinear components in heart rate
variability (HRV). The analysis is based on twenty-three 48-h Holter recordings in healthy …

The accuracy of spectral analysis of heart-rate variability performed on annotated RR
interval lists obtained from several commercial Holter systems was appraised. 5 Tape …

The analysis of fluctuations in heart rate or heart rate variability (HRV) has found
applications in, among others, the study of the neural cardiovascular system and ergonomic …

Spectral estimates of heart rate variability (HRV) often involve the use of techniques such as
the fast Fourier transform (FFT), which require an evenly sampled time series. HRV is …

We present a simple efficient algorithm for the derivation of a heart rate signal from the
electrocardiogram. We demonstrate that the amplitude spectrum of this heart rate signal …

The authors' study focuses on a new method of estimating the heart rate variability (HRV)
which does not require the use of electrocardiogram (ECG) R-wave detection. Contrary to …
