Type 1 myotonic dystrophy (DM1) is a neuromuscular disorder of multiple organ systems with important electrophysiologic (EP) manifestations, leading to a cumulative incidence of sudden death of 6.6%. Due to genetic anticipation, there is a pediatric subset of this patient population. However, most EP research on DM1 patients has been in adults, making cardiac care for pediatric patients difficult and directed by adult guidelines which often leads to cardiovascular implantable electronic device (CIED) implants. We sought to investigate the prevalence of CIEDs in the pediatric DM1 population.
