Eating Disorder (ED) patients who were admitted to
an eating disorders program for a 6-week treatment and
were assessed for changes in heart rate variability
(HRV). Linear heart rate variability measures (HRV)
were determined using Kubios software from 20 minute,
Lead 3 ECG recordings following a 5-minute rest period.
Eighteen patients and 31 controls were included in the
analysis. Results were deemed significant if p<0.05. No
significant differences in HRV parameters were noted for
the control group between Pre- and Post-treatment. For
the ED group, mean RR interval length decreased
significantly compared to the control group (p=0.006).
HF peak frequency increased significantly in the ED
group (p=0.001). High frequency (HF) peak indicated
that the respiratory frequency increased from Pre to Post
measurement. RMSSD tended to decrease (p=0.047) in
the ED group. Hence at admission to hospital the ED
group was more parasympathetic during rest compared
to controls, but they became more sympathetic after the
intervention and thus approached the HRV measures of
the controls suggesting improvement in ANS modulation
of the heart.
