Borderline and Long QT Syndrome in Adolescent Athletes Taking Medications

摘要

Purpose: Adolescent athletes undergo preparticipation screening for long QT syndrome. Medications that are associated with QT interval prolongation are increasingly being prescribed to pre-college students. The side effect profile of these medications during exercise is unknown. The aims of this study were to (1) measure the prevalence of medications known to be associated with QT interval prolongation taken by adolescents participating in athletics and (2) to determine the association between the use of these medications and QT interval prolongation in adolescents participating in athletics.
