Consumer wearable data can support exploratory review only. The HEV diagnosis, temporally confounded with treatment start, remains a material confounder.

Clinical Interpretation
  • ABNORMAL: HRV is NOT higher during deep sleep than during light sleep. Normal parasympathetic dominance during deep sleep is absent - suggests autonomic dysfunction.
