Key result
A turbulence analogy-based cascade model successfully captures the statistical properties and inertial range equivalence of long-term heart rate variability in healthy humans.
A turbulence analogy and cascade model can effectively capture the statistical properties of long-term heart rate variability in healthy humans.
Hypothesis-generating for turbulence models of HRV; no role in clinical practice without validation.
Many complex systems share similar statistical characteristics. In this Letter, a turbulence analogy is proposed for the long-term heart rate variability of healthy humans. Based on such an analogy, the equivalence of an inertial range is found and a cascade model, which captures the statistical properties of the heart rate data, is given.
