Key result
Aging in healthy subjects was associated with a peak in short-term heartbeat interval correlations (alpha1) around 50-60 years and a decrease in deceleration capacity.
Population
180 healthy subjects without health complaints (85 males, 95 females) aged 20 to 89 years.
Design
Cross-sectional
Follow-up
2 nights

May warrant age- and stage-specific norms for heart rate dynamics; leaves open links to cardiovascular outcomes.
Observational (n=180)
Yes
Age-dependent changes in fractal scaling of heartbeat intervals and decreased deceleration capacity should be considered when evaluating cardiovascular risk and autonomic function.
Schumann et al. (2010) conducted an observational in Healthy subjects (n=180). Age and sleep stages was evaluated on Short-term and long-term correlation properties of heartbeat and breathing-interval data (DFA exponent alpha1 and alpha2) and deceleration capacity. Aging in healthy subjects was associated with a peak in short-term heartbeat interval correlations (alpha1) around 50-60 years and a decrease in deceleration capacity.
