Ventricular tachycardia (VT) is a life-threatening arrhythmia that is common to all forms of
heart disease and an important cause of sudden death. Ventricular scars from infarction or …

Background—Catheter ablation of ventricular tachycardia (VT) is effective and particularly
useful in patients with frequent defibrillator interventions. Various substrate modification …

Catheter ablation is now an important option to control recurrent ventricular tachycardias
(VTs). The field has evolved rapidly and is a work in progress. Ablation is often a sole …
