Why the study?
To evaluate heart rate variability in hospitalized patients with suspected or confirmed COVID-19 compared to healthy controls and in relation to proinflammatory cytokines.
Does COVID-19 infection alter heart rate variability compared to healthy controls?
Does COVID-19 infection alter heart rate variability compared to healthy controls?
COVID-19 infection is associated with significant alterations in heart rate variability indicative of autonomic nervous system dysfunction, regardless of viral load confirmation.
Altered HRV in hospitalized COVID-19 patients signals possible autonomic dysfunction; observational findings leave open any role for routine monitoring.
