[QUOTE="BigTex, post: 245480, member: 43589"] Same here, I have been monitoring mine with my FitBit Charge 5. I usually average between 60 and 57. Interesting research being done on HRV: [B]Assessment of physiological signs associated with COVID-19 measured using wearable devices[/B] Aravind Natarajan, Hao-Wei Su, and Conor Heneghan Fitbit Research, 199 Fremont St, Floor 14, San Francisco, CA 94105 (Dated: August 14, 2020) Respiration rate, heart rate, and heart rate variability are some health metrics that are easily measured by consumer devices and which can potentially provide early signs of illness. Furthermore, mobile applications which accompany wearable devices can be used to collect relevant self-reported symptoms and demographic data. This makes consumer devices a valuable tool in the fight against the COVID-19 pandemic. We considered two approaches to assessing COVID-19 - a symptom-based approach, and a physiological signs based technique. Firstly, we trained a Logistic Regression classier to predict the need for hospitalization of COVID-19 patients given the symptoms experienced, age, sex, and BMI.

Data on 1,181 subjects diagnosed with COVID-19 (active infection, PCR test) were collected from May 21 - July 14, 2020. 11.0% of COVID-19 subjects were asymptomatic, 47.2% of subjects recovered at home by themselves, 33.2% recovered at home with the help of someone else, 8.16% of subjects required hospitalization without ventilation support, and 0.448% required ventilation.
