Discussion

Implication

Does not support low-dimensional chaos in healthy HRV; leaves open the drivers of nonlinear determinism for further study.

Structured PICO

Is the variability observed in the normal heart rate due to low-dimensional chaos?

Population

10 healthy subjects

Intervention

Assessment of heart rate variability using ambulatory ECG recordings of consecutive RR intervals at rest in the supine position

Comparator

Ten surrogate time series constructed from each experimental dataset with the same linear dynamics and amplitude distribution

Outcome

Presence of nonlinearities and/or chaotic dynamics (measured by correlation dimension and nonlinear predictability)surrogate

Heart rate variability in healthy subjects is driven by linear correlations and nonlinear determinism rather than low-dimensional chaos.
