Abstract：
:An electrophysiological study (EPS) and a programmed ventricular stimulation (PVS) are strongly recommended and clearly indicated before the implantation of a cardioverter defibrillator (ICD), if patients present with a cardiac arrest and no structural heart disease or a hypertrophic cardiomyopathy. In these patients the prevalence of a curable cause of the cardiac arrest, such as accessory pathways or an idiopathic ventricular tachycardia (VT), is high and the ICD implantation may be avoided. The same is true for patients who present with a cardiac arrest and a short PQ interval or a delta wave. If patients present with wide-complex tachycardias and the diagnosis of VT is unclear, an EPS and PVS are also clearly indicated. If patients have syncope or nonsustained VTs and a structural heart disease, PVS may be used for risk stratification. However, EPS and PVS may be of little use in patients with a structural heart disease and an impaired left ventricular function after a survived cardiac arrest or an unstable VT, which makes them candidates for ICD implantation anyway.
