Abstract
We report the case of 14-year-old boy with X-linked Emery–Dreifuss muscular dystrophy who developed sick sinus syndrome and required placement of an implantable intracardiac cardioverter-defibrillator (ICD) to prevent sudden death. He demonstrated no significant risk factors for sudden death such as depressed left ventricular ejection fraction, or spontaneous or inducible ventricular tachycardia. One month after implantation, the patient experienced one appropriate ICD discharge.
