Invasive electrophysiologic testing: Role in sudden death prediction

Abstract

Programmed ventricular stimulation has dramatically advanced understanding of ventricular tachycardia after myocardial infarction. It remains an important tool for sudden cardiac death risk assessment in certain groups of patients. Its role in patients without infarct-related scar is less clear. Current role of programmed ventricular stimulation, invasive assessment of accessory pathway properties and HV interval measurement is discussed in detail.
