Catheter ablation of monomorphic ventricular tachycardia.

Patients with ventricular tachycardia are subject to frequent recurrences and antiarrhythmic drug therapy has been disappointing. Catheter ablation offers an alternative means of controlling ventricular tachycardia.The origin and pathophysiology of ventricular tachycardia are being defined for newly recognized types of ventricular tachycardia as well as scar-related ventricular tachycardias. The approach to mapping and ablation of ventricular...
