WebQT (QTc) interval; Pediatric and neonatal electrocardiograms differ markedly – in terms of rhythm, morphology, normal findings, normal variants, etc – from adult electrocardiograms. It is crucial to be familiar with normal findings, normal variants, and pathology in neonates, infants and during the childhood years. The QT interval is a measurement made on an electrocardiogram used to assess some of the electrical properties of the heart. It is calculated as the time from the start of the Q wave to the end of the T wave, and approximates to the time taken from when the cardiac ventricles start to contract to when they finish relaxing. An abnormally long or abnormally short QT interval is associated with an increas…
