State-Transition Dynamics in the HR--Deceleration Capacity Feature Space: Passive Assessment of Autonomic Dysfunction from 24-Hour Heart Rate
Autonomic dysfunction is a critical predictor of mortality in aging, Type 2 Diabetes (T2DM), and Congestive Heart Failure (CHF). Active clinical tests such as the Valsalva maneuver and tilt table impose procedural burdens, while standard HRV metrics cannot distinguish transient physiological states from underlying regu...
