An innovative approach for the evaluation of Stress, Pain and Well-being:
HRV measurement during sleep

Offering Clinical Data to Clinicians and Patients
Heart Rate Variability (HRV) is a strong indicator of the autonomic nervous system reflecting the interplay between sympathetic (stress, alertness) and parasympathetic (rest, recovery) activity.
Current methods are limited by external factors and give only a partial view of autonomic function.
Somno-Art® is the new path
to assess HRV during sleep, in a stabilized, spontaneous, and physiological environment, free from external disturbances.
We provide a comprehensive set of HRV indices, including the Analgesia/Nociception Index (ANI), with fully customizable outputs. This allows users to efficiently monitor their patients’ well-being and stress levels over time, offering actionable insights into physiological and autonomic responses.

Advanced HRV Analysis
We perform a comprehensive and customizable analysis of HRV indices applied to any recording regardless of the device used to record cardiac activity, whether it be a Holter monitor, PSG or any other system.
Our HRV report includes:
- Global analysis: mean values of the HRV indices computed over the entire recording
- Time-course analysis: visual representation of the HRV indices across the recording
- Sleep stages related HRV analysis: HRV analysis restricted to N3 and REM+Wake periods, including both global and time-course analyses
