SPARK infers latent cardiac autonomic dynamics from RR intervals, showing physiological information reduces solution variability and reveals distinct autonomic responses.

This paper develops a theoretical framework to analyze cardiac-autonomic regulation using dynamical systems theory and demonstrates its properties through simulations.

The paper identifies autonomic phenotypes in older adults from a high-southern-latitude population using integrated HRV and physiological data, revealing a multidimensional structure of autonomic heterogeneity.
