NCT00622453

Brief Summary

Adult myotonic muscular dystrophy (Steinert's disease) is the most common inherited neuromuscular disorder. Cardiac rhythm disturbances occur frequently in this disease state and may be responsible for up to one-third of deaths. In this study, we intend to evaluate the utility of non-invasive electrocardiographic screening methods and history in predicting serious arrhythmic events.
