Acute hypotensive episodes are common during dialysis sessions, and represent a serious problem. Spectral analysis of heart rate variability (HRV) and systolic blood pressure variability is performed to obtain barorreflex sensitivity (BRS) and to study the behaviour of the autonomic nervous system (ANS) during the hemodialysis. The BRS index in the HF band is significantly different in patients being prone and resistant to hypotension (p<0.05).
