Abstract
The aim of the study was to analyze the behavior of the autonomous nervous system (ANS) during hemodialysis (HD) treatment with two ultrafiltration (UF) profiles: gradually decreasing UF rate and gradually decreasing UF rate. Spectral analysis of heart rate variability (HRV) was used to estimate the mean power in the low frequency (LF) band and the high frequency (HF) band indexes. LF was larger than HF in all patients, which is consistent with a sympathetic nervous system activation response during HD. Although each patient responded differently to each UF profile, the mean values of all indexes from the whole group were similar between the two UF profiles.
