Unmasked type I electrocardiographic pattern of Brugada syndrome after SARS COV -2 (COVID 19) vaccine shot: Is there any relationship with the suspected increased risk of sudden death?

The vaccination used for the prevention of COVID-19 could unmask patients with hidden Brugada syndrome even without febrile episodes. We described a case of unmasking or Brugada syndrome in a female patient after vaccination for COVID-19. A possible relationship with sudden death events requires further study. In people with known Brugada syndrome or in their relatives, we recommend serial electrocardiographic monitoring after the administration of the vaccination dose.
