Key result
A physiological oscillator model established that the length and width of a Poincaré plot are a weighted combination of low- and high-frequency power, linking frequency- and time-domain analyses.
A physiological oscillator model provides a theoretical link between frequency-domain spectral analysis and time-domain Poincaré plot analysis of heart rate variability.

Theoretical linkage may aid HRV research integration; leaves open empirical validation for clinical use.
Brennan et al. (2002) studied Heart rate variability. Physiological oscillator model of HRV vs. Actual R-R intervals was evaluated on Shape of the R-R interval Poincaré plot. A physiological oscillator model established that the length and width of a Poincaré plot are a weighted combination of low- and high-frequency power, linking frequency- and time-domain analyses.
