Abstract
Ventricular cardiac rhythm disorders are potentially life-threatening arrhythmias. Ventricular tachycardia (VT) in patients with structural heart disease carries an increased risk of sudden cardiac death. Interventional radiofrequency catheter ablation is increasingly becoming the focus of treatment for ventricular arrhythmias. So far, no randomized study has been able to demonstrate areduction in mortality; however, depending on the existing cardiomyopathy, interventional VT ablation has proven to be more effective for rhythm stabilization than antiarrhythmic therapy and is subsequently associated with improve quality of life through reduced implantable cardioverter defibrillator (ICD) treatment. The aim of this work is to discuss the pathophysiology, mechanism and treatment of VT with structural heart disease in order to define the role of catheter ablation.
