MIT-BIH Arrhythmia DB, normal sinus rhythm (NSR). 360 Hz single-channel ECG; classic P-QRS-T morphology, ~1 Hz heart-rate with respiratory sinus arrhythmia.
Standard analysis sees: right-skewed; time-irreversible (sharp rises, slow decay); multifractal. The atlas finds no named structure, but the source is distinctively extreme on E8 Lattice:std_profile (+4.2z) — beyond what the standard bank predicts for it.
