Abstract
- Duchenne muscular dystrophy (DMD) is a severe X-linked recessive disorder characterized by rapid progression of muscle wasting and weakness. The disorder is caused by a mutation in the dystrophin gene on chromosome Xp21.1. DMD may be accompanied by heart failure, but conduction abnormalities are uncommon. We report a case of a 28-year- old male patient with DMD who presented with symptoms of bradycardia, chest discomfort and dyspnea. He was diagnosed as having complete atrioventricular block by electrocardiogram. Pacemaker was inserted, and subsequently symptoms and electrocardiogram findings showed improvement.
