Increased QTc dispersion and mortality in uremic patients with acute myocardial infarction.


QT dispersion (the difference between maximum and minimum QT across the 12-lead electrocardiogram [ECG]), which reflects regional variations in ventricular repolarization, is a predictor of arrhythmia and cardiovascular mortality. The present study was undertaken to assess the difference in QT dispersion between uremic and nonuremic patients with acute… (More)
