It leads to syncope or sudden death in young adults with structurally normal hearts. Episodes are preceded by ST-segment elevation in precordial leads V1 and V2. An estimated 18% to 30% of patients carry loss-of-function mutations in SCN5A, the gene that encodes the cardiac sodium channel (1). Anecdotes suggest that fever may be associated with cardiac arrest and preceding electrocardiographic (ECG) changes (Figure) (2, 3).Figure.Typical fever-induced electrocardiographic changes in a patient with the Brugada syndrome.Note fever-induced PR and QRS interval prolongation and elevation ...References1.
