Introduction
The majority of idiopathic Purkinje-related ventricular tachycardias
(VTs) are caused by reentrant mechanisms, and non-reentrant fascicular
tachycardia (NRFT) is a rare form of idiopathic VTs in
adults.1-3) It
is crucial to distinguish NRFT from other idiopathic reentrant VTs for
the accurate diagnosis as well as the effective treatment. However,
there is no information about the
electrophysiological studies and the treatment effect in the
pediatric-onset NRFT. We herein report a pediatric case of refractory
NRFT that was successfully treated by the catheter mapping and ablation.
