Sudden cardiac death (SCD) is a frequent cause of mortality in the developed countrys. In the majority of cases the reason of SCD is ventricular tachycardia (VT). The gold standard of VT therapy is presently the implantable defibrillator-pacemaker (ICD) implantation. Secunder prevention indication is present in those patients who have already survived an SCD or a VT episode, and those patients, whose chance is high to have an SCD episode or a VT episode have primary prevention indication. The other nonpharmacological therapy of VTs is catheter ablation. During an electrophysiological study foci of idiopathic VTs are identified, or in case of postinfarction VTs scar-related reentry circuits, isthmus regions and exit points are mapped with electrophysiological and electroanatomical methods. Cathter ablation is a curative technique in idiopathic VTs but only adjunctive therapy to an ICD in the majority of postinfarction VT patients. Both ICD and catheter ablation improves significantly the mortality and quality of life in the postinfarction patient group.
