Implication

May refine research assessment of autonomic regulation; leaves open clinical adoption pending prospective validation.

Key Points

Review the application and methodological principles of multi-signal system identification used to quantitatively characterize neural cardiovascular regulation from beat-to-beat variability.
Synthesized literature from the past two decades applying digital signal processing and system identification to cardiovascular dynamics.
Evaluated analytic frameworks for probing sinoatrial node properties, respiratory sinus arrhythmia, and baroreflex control of sympathetic nerve activity, heart rate, and total peripheral resistance.
Multi-signal system identification enables dynamic characterization of autonomic coupling between physiological perturbations and regulatory responses beyond single-signal spectral metrics.
Current literature highlights the necessity of developing methods capable of handling nonlinear and time-varying cardiovascular dynamics, rigorous identification validation, and understudied neural pathways.
