A prolonged QT interval in the neonatal period and during infancy is associated with higher mortality rates, independently of the appearance of symptoms. This suggests the opportunity of a prophylaxis with beta-blockers in this population. QT interval dispersion is a useful clinical tool to predict the efficacy of antiadrenergic therapy. However, the effects of antiadrenergic interventions on QT interval and QT interval dispersion in newborns are not known. Standard 12-lead electrocardiograms… CONTINUE READING
