What It Is

PhysioNet Fantasia RESP channel. Real chest/abdomen respiratory effort at 250 Hz, 3 subjects (~5.4M samples). Smooth quasiperiodic with breath-to-breath variability.

Interpretation

Standard analysis sees: long-range memory (persistent). The atlas finds no named structure, but the source is distinctively extreme on Bispectrum:off_diagonal_ratio (-2.9z) — beyond what the standard bank predicts for it. It sits beside Langevin Double-Well in the atlas (standard-bank rank 20) — a neighbor conventional features miss.
