- The Cardiac Stability Index combines Lyapunov exponent, recurrence determinism, and Shannon entropy into a scalar score between 0 and 1. — Cardiac Stability Theory: An Axiomatically Grounded Framework for Continuous Cardiac Health Monitoring via Smartphone Photoplethysmography
- CSI uses positive weights that sum to one across its three component terms. — Cardiac Stability Theory: An Axiomatically Grounded Framework for Continuous Cardiac Health Monitoring via Smartphone Photoplethysmography
- CSI computation reconstructs phase-space dynamics using delay selection, Takens embedding, Lyapunov estimation, recurrence quantification, entropy, and weighted aggregation. — Cardiac Stability Theory: An Axiomatically Grounded Framework for Continuous Cardiac Health Monitoring via Smartphone Photoplethysmography
- CSI alone is not a monotone detector of fibrillatory chaos because fibrillatory values can exceed typical healthy values. — Cardiac Stability Theory: An Axiomatically Grounded Framework for Continuous Cardiac Health Monitoring via Smartphone Photoplethysmography
- Empirical support for CSI direction includes higher NORM CSI than MI CSI and rhythm discrimination with AUROC 0.89. — Cardiac Stability Theory: An Axiomatically Grounded Framework for Continuous Cardiac Health Monitoring via Smartphone Photoplethysmography
