N2 - Objectives. The aim of the study was to assess if QT dispersion and RR interval on the standard 12-lead electrocardiogram (ECG) predict cardiac death and late arrhythmic events in postinfarction patients with low left ventricular ejection fraction (LVEF). QT dispersion on a standard electrocardiogram (ECG) is a measure of repolarization inhomogeneity, but its prognostic meaning in myocardial infarction (MI) survivors is unclear, especially in patients with left ventricular dysfunction. RR interval has been shown to predict mortality in post-MI patients, but its prognostic power has not been compared with other noninvasive risk factors. Methods. Retrospective cohort study. Ninety patients were identified, from a series of 547 consecutive postinfarction patients admitted to our institution for phase II cardiac rehabilitation, as having a LVEF of
