A Case of Myotonic Dystrophy with Prolonged Atrial Flutter

Myotonic dystrophy is a multisystemic disorder inherited as an autosomal dominant trait. The characteristic clinical features include the presence of myotonia, atrophy of the muscles of the face and the sternocleidomastoids and numerous nonmusclar manifestations such as cataracts, frontal baldness, gonadal dysfunctions and cardiac abnormalities. We experienced one case of myotonic dystrophy with prolonged atrial flutter in 30-year-old male who was admitted because of palpitation. We present this case with reviewing literatures.
