ABSTRACT
We describe the case of a 61-year-old woman who underwent successful catheter cryoablation of a symptomatic Hisian ectopy. Diagnosis was based on features of the HV interval assessed from a bipolar recording during mapping. The location of the arrhythmic focus was identified using simultaneous unipolar and bipolar recordings of the His electrogram. This case report highlights the use of 2 new criteria for the diagnosis and mapping of Hisian ectopy, and the successful use of cryothermia for the ablation of extrasystoles arising from the His bundle.

Las vías accesorias múltiples en pacientes con síndrome de Wolff-Parkinson-White son de presentación poco frecuente y en general presentan un riesgo aumentado de fibrilación ventricular. Describimos un caso excepcional en un paciente portador de 4 vías accesorias auriculoventriculares asociadas a fibras fasciculoventriculares en quien realizamos ablación por radiofrecuencia
