Handheld mobile biofeedback of heart rate variability in patients with chronic insomnia disorder – a pilot study

Introduction: The hyperarousal concept in patients with insomnia has been tested by measuring autonomous variables, including electrocardiogram (ECG)-derived heart rate and heart rate variability. In stress-related insomnia an elevated nocturnal sympathetic activity was found, while parasympathetic activity was reduced. In this Pilot-study we tested the usefulness of a mobile heart-rate-variability (HRV) biofeedback device in outpatients of a specialized sleep clinic.
