Junctional ectopic tachycardia and type 1 Brugada ECG in a pediatric patient: Casuality or causality?

A 5-year-old male was admitted for tachycardia, toothache and fever. The 12-lead electrocardiogram showed a narrow QRS complex tachycardia. Following adenosine administration, the diagnosis of junctional ectopic tachycardia (JET) was established. Sinus beats showed a type 1 Brugada ECG. In the case herewith reported, JET presentation was unusual, occurring in a patient with no history of congenital heart disease or heart surgery. In the last years, Brugada Syndrome (BrS) was also correlated to various supraventricular arrhythmias. The peculiarity of the case is the first time reported association between JET and fever-induced type 1 Brugada ECG.
