Major risk factors for developing these arrhythmias include cardiac structural abnormalities and coronary artery disease (CAD) (see Fuster and Hurst’s Central Illustration). Moreover, a number of inherited channelopathies can predispose to these arrhythmias and should be considered in the context of a structurally normal heart. Ventricular arrhythmias can range from idiopathic premature ventricular complexes, to monomorphic ventricular tachycardia (VT), to ventricular fibrillation (VF). Management of ventricular arrhythmias requires a comprehensive approach that may involve multiple therapies, including an implantable cardioverter defibrillator (ICD), antiarrhythmic medications, catheter ablation, and/or autonomic modulation. The decision-making process for management depends highly upon the presence of underlying structural abnormalities.
