Implication
May aid age-adjusted HRV interpretation; leaves open longitudinal validation for clinical use.

How do linear and nonlinear heart rate variability parameters change with aging in normal subjects?
P
Population
Normal subjects divided into four age groups
I
Intervention
Heart rate variability (HRV) analysis using time domain, frequency domain, and nonlinear parameters (Poincare geometry, ApEn, LLE, DFA)
O
Outcome
Ranges of linear and nonlinear HRV parameters across different age groupssurrogate
Heart rate variability analysis using nonlinear parameters demonstrates that cardiac autonomic regulation becomes less chaotic and decreases with normal aging.
