A smartwatch that can track heart rate can be used to monitor disease progression in people with COVID-19 and may predict how sick they will become, a study published Tuesday found.
Heart rate per step tracked with a smartwatch, a measure of heart and lung function, increased after COVID-19 symptom onset and was higher in study participants who reported a cough, data published Tuesday by Cell Reports Medicine showed.
