Abstract

Familial atrial fibrillation is inherited and sporadically occurs in the paediatric population. Generally, fibrillated wavelets are reported at a frequency of approximately 6 Hz. Herein, we report a familial case presenting rapidly fibrillated wavelets at frequencies of approximately 12 to 30 Hz associated with KCNQ1 and SCN5A mutations.
