Electrocardiographic findings in Rett syndrome: an explanation for sudden death?

Author information

Department of Pediatrics, Baylor College of Medicine, Houston, Texas 77030.


Girls with Rett syndrome had significantly longer corrected QT intervals (p < 0.001) and more T-wave abnormalities (p < 0.001) than were found in age-matched healthy girls. With advancing stages of the syndrome, the proportion of corrected QT interval prolongations and T-wave changes increased. The findings suggest a possible cardiac basis for sudden, unexpected death in Rett syndrome.
