Idiopathic Ventricular Fibrillation - How to Treat?

Sudden cardiac death is a regular occurrence in clinical medicine. Idiopathic ventricular fibrillation (VF) is a relatively rare subgroup, because it requires exclusion of structural heart disease as well as primary arrhythmia syndromes to establish this diagnosis. In some cases, catheter ablation of premature ventricular complexes may be curative. Moreover, some pharmacological treatment options like quinidine in early repolarization syndrome show promising preliminary results. However, ICD implantation is in all but very few cases of patients with idiopathic VF absolutely indispensable.
