We studied variations in the prevalence of prolonged QT, based on different common definitions, in a large nonhospitalized population, and compared our re...
متن کاملProlonged QT interval in Rett syndrome.
Rett syndrome is a severe neurodevelopmental disorder of unknown aetiology. A prolonged QT interval has been described previously in patients with Rett syndrome.

متن کاملRepolarization Heterogeneity: Beyond the QT Interval
R esearch over the past 2 decades has suggested that significant differences exist in the action potentials of endocardial, epicardial, and mid-myocardial (M) cells that comprise the ventricular myocardium. Relative differences in the time course of repolarization of these 3 cell types, referred to as transmural dispersion of repolarization (TDR), is largely responsible for the inscription of t...
