Abstract
BACKGROUND

Cardiac arrhythmias, including bradyarrhythmias, have been described as manifestations of coronavirus disease 2019 (COVID-19). Herein, we present a case of junctional bradycardia secondary to possible sinus node dysfunction in a patient with COVID-19.

CASE SUMMARY

The patient was a 32-year-old woman with no significant medical history. On the third day of hospitalization, she developed junctional bradycardia while being hemodynamically stable. The episodes of nodal dysrhythmia with a low heart rate persisted for the next few days and were associated with elevated levels of systemic inflammatory markers. The patient received antiviral and anti-inflammatory treatments for the viral infection but no antiarrhythmic medications. She had a normal sinus rhythm on day 12.

CONCLUSION

Cardiac rhythm monitoring, focusing on the association between cardiac arrhythmias and the systemic inflammatory response, is important in COVID-19 patients.

Core Tip: A variety of cardiovascular manifestations of COVID-19 have been described. Among these, bradyarrhythmias should be considered one of the main complications and clinical features of COVID-19. Herein, we present a case of junctional bradycardia in a patient with COVID-19. Bradyarrhythmias in COVID-19 patients has been linked to increased systemic inflammatory response and the subsequent dysfunctioning of the sino-atrial node. The inflammatory biomarker and cardiac rhythm monitoring should be considered in patients with COVID-19 during different stages of care.
