Quantifying errors in spectral estimates of HRV due to beat replacement and resampling.

Quantifying errors in spectral estimates of HRV due to beat replacement and resampling.

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 calculated from the variations in the beat-to-beat (RR) interval timing of the cardiac cycle which are inherently irreg...
