Patients with ischemic heart disease and left ventricular systolic dysfunction (ICM), dilated (DCM), hypertrophic (HCM), or arrhythmogenic right ventricular cardiomyopathy (ARVCM) carry a high risk of sudden cardiac death (SCD). Ventricular tachyarrhythmias are most often the cause of SCD, which can be treated with internal cardioverter defibrillators (ICDs). However, a great proportion of these high-risk patients will never experience potentially lethal ventricular arrhythmias, and as such will never be in need of these devices. Given the risks, inconvenience, and costs of ICDs, markers that adequately stratify patients according to their risk of SCD are needed. Programmed ventricular stimulation (PVS) has long been used to identify the patients' risk of SCD. However, the prognostic ability of PVS is only modest and the negative predictive value is poor. As far as patients with ICM are concerned, recent data from the MUSTT and MADIT II trials demonstrate that in patients with a left ventricular ejection fraction between 30% and 40%, inducibility by PVS can help to identify patients who are at particularly increased risk of SCD. The value of PVS in patients with DCM, HCM, and ARVCM for risk stratification of SCD is less clear and the available data even more limited. In these patients, the inducibility of ventricular tachyarrhythmias does not clearly correlate with VT/VF (ventricular tachycardia/ventricular fibrillation) risk, and more importantly, noninducibility does not portend good prognosis. The current German guidelines appreciate these uncertainties of PVS for risk stratification with class IIb recommendations in certain patients with ICM, HCM or ARVCM. In the future, combining the results of invasive PVS with other noninvasive parameters may improve its prognostic value. Furthermore, expanding the role of PVS to guiding therapeutic ablation of ventricular arrhythmias may influence patient's future risk of SCD.
