Heart rate corrected QT interval in newborn electrocardiogram

There have been numerous debates on the best formula for heart rate (HR) correction of QT interval on electrocardiograms (ECG). Many previous studies have compared different commonly used correction formulae in adults (1-4), children and adolescents (5,6). Lately, we have also seen studies on the QT correction formulae in even younger populations, such as infants (7,8), but there has been no study on newborns (younger than 30 days of age).
