The combination of noninvasive studies and electrophysiological testing for predicting arrhythmic events was evaluated prospectively in 303 patients who survived acute myocardial infarction. Of 67 patients who were eligible for electrophysiological study on the basis of at least two important risk markers, 47 underwent testing. Inducibility of sustained monomorphic ventricular tachycardia at a rate lower than 270 beats per minute was the strongest independent predictor of events. With good sensitivity, the combination of noninvasive testing and electrophysiological study identified a group of postinfarction patients at sufficiently high risk to be considered candidates for invasive therapy.
