Corrected QT Intervals in the Pediatric Emergency Department

The QTc values displayed on unconfirmed pediatric ECGs are often different from those subsequently adjudicated by cardiologists, and may substantially influence clinical impressions and decision-making by primary providers. Providers in the pediatric ED should be aware that variable methods and algorithms "behind the scenes" cause these variations, and have tools to confirm QTc values in advance of delayed confirmation by a cardiologist.
