Automated QT analysis on Holter monitors in pediatric patients can differentiate long QT syndrome from controls

摘要

BackgroundBorderline QTc is a common referral to the pediatric cardiology clinic. Evaluation is challenging due to significant overlap of normal and abnormal QTc ranges. We hypothesized that automated QT analysis on Holter could differentiate between patients with long QT syndrome (LQTS) and healthy controls.
