- HeartSpan equals chronological age minus Cardiac Dynamical Age. — Cardiac Stability Theory: An Axiomatically Grounded Framework for Continuous Cardiac Health Monitoring via Smartphone Photoplethysmography
- HeartSpan is derived from age-CSI regression and compares observed CSI to an age-normative curve. — Cardiac Stability Theory: An Axiomatically Grounded Framework for Continuous Cardiac Health Monitoring via Smartphone Photoplethysmography
- HeartSpan is intended for trend detection rather than single-measurement diagnosis. — Cardiac Stability Theory: An Axiomatically Grounded Framework for Continuous Cardiac Health Monitoring via Smartphone Photoplethysmography
- Thirty-day hourly averaging is proposed to reduce per-measurement noise substantially. — Cardiac Stability Theory: An Axiomatically Grounded Framework for Continuous Cardiac Health Monitoring via Smartphone Photoplethysmography
- The age-CSI slope may overstate age effects because it was estimated from a clinically mixed PTB-XL cohort. — Cardiac Stability Theory: An Axiomatically Grounded Framework for Continuous Cardiac Health Monitoring via Smartphone Photoplethysmography
