(HealthDay News) — There are alterations in physiologically based parameters of heart rate around the time of COVID-19 symptom onset, which can differentiate symptomatic and healthy periods, according to a study published in the April 19 issue of Cell Reports Medicine.
Caleb Mayer, from the University of Michigan in Ann Arbor, and colleagues adapted a validated algorithm, developed to estimate daily circadian phase from wearable heart rate and step data. The algorithm estimates six total parameters; these parameters were estimated each day the patient had wearable heart rate data. A dynamic profile of the parameters was recovered for each individual, before and after COVID-19 infection.
The researchers observed significant alterations in the separate physiological features of basal heart rate, heart...
