Quantification of Autonomic Nervous Activity During Hemodialysis

April 25, 2016 updated by: Yoshihiro Tsuji, University of Hyogo

Quantification of Autonomic Nervous Activity by Heart Rate Variability and Approximate Entropy in High Ultrafiltration Rate During Hemodialysis

This study assesses autonomic nervous system function by power spectral analysis of RR interval dynamics in ultrafiltration subjects without blood pressure variation.

Detailed Description

Variations over time in autonomic nervous activity due to differences in ultrafiltration rate will be evaluated by measuring heart rate variability in hemodialysis patients without blood pressure variations during HD session.

The subjects will be divided into 3 groups, those with UFR < 10 ml/hr/kg; ≥10 ml/hr/kg but ≤ 15 ml/hr/kg; and >15 ml/hr/kg, and Holter ECG are recorded continuously during HD session using frequency analysis of RR intervals.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The outcome measures was low frequency power (LF, ms2) to high frequency power (HF, ms2) ratio (LF/HF ratio) of heart rate variability. The three subject groups with difference ultrafiltration were compared by LF/HF ratio during hemodialysis session.
Time Frame: 4 hours
Variations over time in autonomic nervous activity due to differences in ultrafiltration rate will be evaluated by measuring heart rate variability.
