Background: The presence of cardiac manifestations, including bradycardia, has been described as a manifestation of coronavirus disease 2019 (COVID-19). Our case report describes a case of sinus bradycardia secondary to possible sinus node dysfunction in an otherwise asymptomatic patient with COVID-19.
Case presentation: We report the case of an unvaccinated 33-year-old female hospitalized due to bradycardia after 4 days of testing positive for COVID-19. She presented with a 1-day history of transitory lightheadedness and dizziness with no other associated symptoms. Sinus bradycardia was recorded on admission, heart rate 52/min that later dropped to 35/min on the second day of admission. Secondary causes of bradycardia were excluded based on the absence of relevant evidence from laboratory work-up and echocardiographic examination.
Decision‐making: We recommend baseline ECG monitoring in hospitalized COVID-19 patients, regardless of disease severity, to assess for potential cardiac manifestations.
Conclusion: Cardiac rhythm monitoring is an essential component of staying vigilant against potential complications. It raises the question of how physicians should respond to a patient with marked bradycardia and when should they intervene?
