title: Value of the electrocardiogram in determining cardiac events and mortality in myotonic dystrophy.
abstract: Electrocardiograms were recorded at baseline and regular intervals in 53 patients with myotonic dystrophy who were followed for a mean of 6.3 +/- 4.0 years. Patients with cardiac events had a significantly prolonged PR interval (p <0.001), a later age of onset of neuromuscular symptoms (p <0.05), and were older (p <0.005).
