Conclusion
We successfully diagnosed and
ablated NRFT originating from the left posterior fascicle in a child.
NRFT is a controllable VT not to be over\souttlooked when a 12-lead
electrocardiogram shows relatively narrow QRS tachycardia with a right
bundle branch block-type configuration even in the pediatric setting.
