Risk Stratification Using Heart Rate Turbulence and Ventricular Arrhythmia in MADIT II: Usefulness and Limitations of a 10‐Minute Holter Recording

Abstract

In postinfarction patients with severe left ventricular dysfunction, frequent VPBs are associated with increased risk of mortality and with appropriate ICD therapy. HRT obtained from 10-min Holter ECG showed a trend toward the association with mortality in univariate analysis but HRT parameters were not predictive of the outcome in multivariate analyses.
