Heart Disease as the Presenting Feature in Myotonia Atrophica.

Nearly 20 years ago Evans (1944) suggested that the cardiac abnormalities that are associated with myotonia atrophica might in some cases be an important aid to the early diagnosis of this disease. This report concerns a patient who was first thought to be a case of non-specific myocarditis, but who later proved to be one of cardiomyopathy due to myotonia atrophica after a family history of thi...

Observations on a case of myotonia paradoxa.

Myotonia fluctuans.

Autosomal-dominantly inherited nondystrophic myotonic disorders are an interesting group of muscle diseases that provide considerable opportunity for future molecular genetic studies to identify the genes responsible for specific membrane functions. A family with such a myotonic disorder is described with features that are distinctly different from myotonia congenita and paramyotonia congenita....
