Background: Heart rate variability (HRV) test is in widely
used for measurement of autonomic nerve system.
Although the standard measurement time for short-term
HRV analysis is regarded as 5 minutes, it could be varied
depending on the clinical situation. Thus, we examined that
the valid minimum measurement time for HRV
through comparison of HRV among 10 segments per 30
seconds from 30 seconds to 300 seconds.
Methods: The study included 1,457 adult participants who
visited the health promotion center in Seoul, Korea
from the March 2009 to December 2012. The variables of
the time domain and frequency domain analysis of
HRV among 10 segments from 30 seconds to 300 seconds
were compared using one-way ANOVA test with
post-hoc analysis.
Results: Compared with 5-minute (300 seconds) HRV, the
components of HRV measurement were statistically
equal in condition with 180 seconds for standard deviation
of all normal-to-normal interval (SDNN), 270 seconds
for NN50, 180 seconds for total power, 180 seconds for low
frequency power in normalized units (LFn),
and 180 seconds for high frequency power in normalized
units (HFn), respectively.
Conclusions: Our results suggest that the minimum duration
of HRV measurement might be more or than 180
seconds.
