Key result
A simple reaction time task significantly decreased the standard deviation of all interbeat intervals and high-frequency measures of heart rate variability in both young and older adults (P<0.05).
Why the study?
Does an attention-demanding task alter short-term heart rate variability differently in young versus older adults?
Cross-Sectional (n=32)
Does an attention-demanding task alter short-term heart rate variability differently in young versus older adults?
p-value: p=<0.05
Cardiac autonomic modulation during provocative stress shows similar physiologic responses in both young and older adults, despite older adults having lower overall heart rate variability.
No takes yet. Share an insight, caveat, or question.
Attention tasks reduce short-term HRV similarly in young and older adults; leaves open whether baseline differences alter clinical risk interpretation.
R. Wood (2002) reported a cross-sectional. Simple-reaction time task vs. Rest was evaluated on Standard deviation of all interbeat intervals and spectral measures of heart rate variability (p=<0.05). A simple reaction time task significantly decreased the standard deviation of all interbeat intervals and high-frequency measures of heart rate variability in both young and older adults (P<0.05).
