Xana ™ has developed and clinically validated a wearable photoplethysmography (PPG) sensor with its property algorithms embedded to help doctors for a better diagnosis, as well as allow the personalization of the treatments.

Xana ™ has developed and validated its own property algorithm for monitoring the heart rate variability (HRV).

It,s well known that HRV has the potential to be used as a physiological indicator of the nervous function as well as the cardiological health but the current wearable systems are not sufficiently reliable.

To solve this problem, our R& D team led by our Medical Director, Dr. David Calvo, MD, Ph.D., who is an internationally reputed cardiologist with over 20 years of experience researching the cardiac physiology,  has created the Heart Rate Variability Gained Index (HRV-GI) ™ with the goal to offer both doctors and patients a reliable indicator to improve the current control of our cardiac health as well as the personalization of the neurostimulation systems.
