    Author: Tarvainen MP, Ranta-Aho PO, Karjalainen PA.
    Journal: IEEE Trans Biomed Eng; 2002 Feb; 49(2):172-5. PubMed ID: 12066885.
    Abstract:
    An advanced, simple to use, detrending method to be used before heart rate variability analysis (HRV) is presented. The method is based on smoothness priors approach and operates like a time-varying finite-impulse response high-pass filter. The effect of the detrending on time- and frequency-domain analysis of HRV is studied.
