Uncompromising precision from one wrist only
According to the Standards of measurement, physiological interpretation, and clinical use  heart rate variability has considerable potential to assess the role of autonomic nervous system fluctuations in normal healthy individuals and in patients with various cardiovascular and non-cardiovascular disorders.
Prof. Iwona Cygankiewicz et al. mentioned that heart rate variability provides indirect insight into autonomic nervous system tone, and has a well-established role as a marker of cardiovascular risk. HRV analysis is being used for clinical and prognostic application in diabetes, stroke, multiple sclerosis, muscular dystrophies, Parkinson’s disease and epilepsy.
To comply with the above mentioned Standard, it was required to use ECG sensors with sampling rate >100 Hz. Thus it was impossible to use optical PPG sensors for collection of reliable data. In the same time the existing Holter monitors and ECG patches were inconvenient for longitudinal follow-up.
And so our journey began.
Since 2016 the team of experimental physicists, hardware and software engineers, clinical researchers and regulatory affairs specialists, invented and developed ready to use sensor and software to both meet the Standard requirements and provide convenience in data collection.
