Congenital junctional ectopic tachycardia (JET) is a rare arrhythmia due to an automatic focus usually located within the His bundle. This report describes a patient in whom JET was diagnosed at 1 month of age: antiarrhythmic drugs succeeded in lowering tachycardia rate, resulting in an apparently stable condition. At 12 months, however, the child experienced fainting episodes; an ECG performed during one such episode revealed repetitive non-sustained runs of wide QRS tachycardia, a pattern highly suspicious for proarrhythmia. Drugs were withdrawn and the patient underwent successful catheter ablation of the junctional focus with preservation of normal A-V conduction.
