Conditions We Treat: Myotonic Muscular Dystrophy (Myotonic Dystrophy)

Myotonic muscular dystrophy is the most common form of adult-onset muscular dystrophy, a condition where muscles degenerate or weaken and deteriorate. One of the features of myotonic dystrophy is the inability to relax muscles. It can also cause an abnormal heartbeat (arrhythmia) and weaken the heart muscle.

Myotonic Muscular Dystrophy: What You Need to Know

  • Myotonic dystrophy can involve many physical functions, including skeletal muscles, the digestive system, breathing and vision.
  • Treating myotonic dystrophy requires a multidisciplinary team from the departments of neurology, cardiology, pulmonology and others as appropriate.
  • If myotonic dystrophy leads to arrhythmia, your doctor will recommend treatment by an electrophysiologist — a cardiologist specializing in electrical systems of the heart.
  • But because rhythm disorders often progress quickly, it’s best for an electrophysiologist or cardiologist to follow you (alongside your other doctors) even before you show signs of arrhythmia.
