To sleep perchance to dream unusual bradyarrhythmia in an adolescent

Abstract

Connective tissue disorders may involve the conduction system. A 16-year-old patient with known mixed connective tissue disorder (MTCD) presented with bradyarrhythmia. Initially, we considered inflammatory conduction system disease, but unusual clinical course led to further evaluation. She had a REM-sleep related disorder. This rare parasomnia has never been described in childhood but may not be uncommon.
