Three-dimensional mapping discovered arrhythmic substrate missed in the
initial diagnosis of idiopathic ventricular fibrillation
Management of idiopathic ventricular fibrillation (IVF) is challenging
because arrhythmic substrate may be missed; therefore, careful follow-up
and reassessment are necessary. Three-dimensional mapping would be
useful for reassessment of IVF because it revealed an arrhythmic
substrate in a patient, 12 years after his initial diagnosis of IVF.
