## What is CardioRead HRV?

Ease of use heart rate variability (HRV) self-measurement with paced breathing guidance allows for an all important determination of resonant frequency to optimize individual HRV training.  

The comparable HRV statistics allow users to observe graphed history trends and easily export your raw data files for post-analysis (i.e., Kubios).  Individual HRV time and frequency domain measures can be an important component of personal health education and stress reduction. 

Frequent self-assessments allow for a private and consistent method of tracking personal autonomic nervous system balance. HRV training has been shown in the international research to support school children performance, healthcare worker resilience and reduced absenteeism, athlete recovery, executive performance, stress reduction, pain, and several other conditions.  

HRV testing and biofeedback training is arguably one of the single more important self-health and wellness promoting exercises you can do.
