Treatment for ventricular tachycardia in the absence of structural heart disease

Abstract

Background. According to the recent data in up to 10% of the patients with ventricular tachycardia (VT) there is an absence of structural heart disease. Several types of VT could be present in such patients: right ventricular outflow tract (RVO T) VT, caticholaminergic polymorphic VT, idiopathic left VT, Brugada syndrome, long QT syndrome. According to the VT type the management can be pharmacological therapy, radio-frequency ablation, implantation of cardioverter defibrillator or a combination of them. The decision about the management is based on the type of VT, data obtained from echocardiography, magnetic resonance imaging (MRI) and electrophysiological study (EPS).
