Brugada syndrome presents mainly in adulthood,and sudden death occurs mainly at rest or during sleep.It is uncommon in childhood,especially with atrial flutter as the first manifestation.In this article,we report a case of a 13-year-old child with atrial flutter as the first manifestation,without underlying cardiac disease,who developed Brugada-like electrocardiographic changes during the treatment of propafenone,and genetic testing revealed the suspected mutant genes SCN5A(c.2834A＞G[p.D945G]).Present case and related literature review might improve the awareness of clinicians on the inducing factors of Brugada syndrome and related a variety of cardiac arrhythmias,the importance of electrocardiogram monitoring during the application of antiarrhythmic drugs,and provide guidance and close follow-up strategies to this high-risk group,so as to avoid the occurrence of adverse events in these patients.
