title: [Idiopathic tachycardia originated in left ventricle].
abstract: BACKGROUND
  Idiopathic ventricular tachycardia occurs in patients with no structural heart disease and may originate in left of right ventricle.
  
  
  OBJECTIVE
  To report our experience with this condition.
  
  
  METHODS
  We report six patients (five male), aged 35 years old as a mean, with idiopathic left ventricular tachycardia that were subjected to conventional electrophysiological studies with atrial and ventricular stimulation programs and radiofrequency fulguration, between December 1993 and May 1996.
  
  
  RESULTS
  The mean lapse of disease was 24 months and five patients received antiarrhythmic medications previously. All tachycardias had a morphology with an image of right bundle branch block. Radiofrequency fulguration was done after obtaining a satisfactory pace mapping of at least 11 of the 12 superficial EKG derivations. The procedure was successful in five patients and two had a relapse. One of the relapsed patients was successfully fulgurated again.
  
  
  CONCLUSIONS
  Radiofrequency fulguration for idiopathic ventricular tachycardias is a safe and effective therapeutic procedure.
