title: Myotonia dystrophica and mitral valve prolapse.
abstract: Two siblings are described, both afflicted with myotonia dystrophica and mitral valve prolapse. This family supports the recent association of these two familial diseases. One of the siblings had severe conduction disease and recurrent ventricular tachycardia, possibly reflecting potentiation of arrhythmia, because of the association of these two familial diseases.
