An advanced detrending method with application to HRV analysis

IEEE Trans Biomed Eng. 2002 Feb;49(2):172-5. doi: 10.1109/10.979357.


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.
