Insights
This report details a rare case of ventricular fibrillation (VF) arrest in an asymptomatic patient with coronavirus disease 2019 (COVID-19). This finding is significant as it occurred without prior cardiac history or symptoms.
Area of Science:
- Cardiology
- Infectious Diseases
- Critical Care Medicine
Background:
- Cardiac involvement in coronavirus disease 2019 (COVID-19) is recognized, particularly in severe cases among hospitalized patients.
- Previous research has focused on cardiac complications in critically ill COVID-19 patients.
Observation:
- A case of sudden cardiac arrest due to ventricular fibrillation (VF) is presented.
- The patient was asymptomatic and incidentally diagnosed with COVID-19.
- The patient had no prior history of cardiac disease and a normal cardiac workup.
Findings:
- This is the first reported instance of VF arrest in a patient with incidentally detected COVID-19.
- The case highlights a potential, previously undocumented, cardiac manifestation of COVID-19 in an asymptomatic individual.
Implications:
- This case suggests that COVID-19 may present with serious cardiac arrhythmias even in asymptomatic individuals.
- Further investigation into subclinical cardiac effects of COVID-19 is warranted.
- Clinicians should consider COVID-19 as a potential factor in unexplained cardiac arrests, even in the absence of typical symptoms.
Abstract:
In this report, we present a case of ventricular fibrillation (VF) arrest in an asymptomatic coronavirus disease 2019 (COVID-19) patient with no cardiac history and normal cardiac workup. Cardiac involvement in COVID-19 has been described previously in hospitalized patients with severe COVID-19. To our knowledge, this is the first report to describe VF arrest in a patient who was incidentally found to have COVID-19.
