Key result
COVID-19 infection was associated with a decrease in heart rate and a paradoxical decline in heart rate variability compared to the patient's baseline.
Why the study?
This study investigated heart rate and heart rate variability changes in a patient with COVID-19.
Does COVID-19 infection alter heart rate and heart rate variability compared to historical baseline?

Does COVID-19 infection alter heart rate and heart rate variability compared to historical baseline?
An abrupt decline in HRV and a decrease in HR may signal the onset of COVID-19 before common symptoms appear.
Case observation of reduced HR and paradoxical HRV decline in COVID-19 should not change practice; leaves open need for larger studies on autonomic effects.
This case study investigates the heart rate (HR) and heart rate variability (HRV) in a patient with coronavirus disease 2019 (COVID-19). We report the case of a 58-year old male who contracted COVID-19. During his disease, 24-hour Holter electrocardiography (ECG) was performed continuously. For comparison, his 24-hour Holter ECGs from the previous 10 years were available. In this patient, COVID-19 was associated with a decrease in HR and a paradoxical decline in HRV. An abrupt decline in HRV and a decrease in HR may signal the onset of COVID-19 before common symptoms such as dry cough or fever appear. In addition, HRV and HR measurements may help to evaluate the course of the disease.

Buchhorn et al. (2020) conducted a case report in Coronavirus Disease 2019 (COVID-19) (n=1). COVID-19 vs. Previous 10 years (baseline) was evaluated on Heart rate (HR) and heart rate variability (HRV). COVID-19 infection was associated with a decrease in heart rate and a paradoxical decline in heart rate variability compared to the patient's baseline.
