Catheter Ablation and Implantation of the Implantable Cardioverter Defibrillator(Current Topics on Cardiac Arrhythmias)

Catheter ablation is useful therapy for medically refractory tachyarrhythmias but still remains experimental. Clinically, direct current and radiofrequency are used as the source of the energy of the ablation. Two cases of therapy of tachyarrhythmia (WPW syndrome, ventricular tachy cardia) were reported. Implantable cardioverter defibrillator (ICD) is indicated to prevent sudden death from tachyarrhythmias in drug-refractory cases, or not cured by catheter ablation or operation. A case of an implantation of the ICD for idiopathic ventricular fibrillation was presented
