    Prolongation of the QT interval is the cause of about 10% cases of sudden infant death syndrome (SIDS) in newborns but it is also responsible for about 5% of sudden deaths in adults. LQTS is associated with life threatening arrhythmias such us torsade de pointes ventricular tachycardia or ventricular fibrillation (VF) leading to sudden death. Congenital causes (channelopathies) of LQTS are associated to mutations with different hereditary pattern according affected gene but it has been proven that several drugs and electrolytic alterations can significantly increase the QT interval. However, the cost-effectiveness of neonatal electrocardiographic (EKG) screening has been questioned and despite studies made in newborns there is still no consensus about the best moment to make and electrocardiographic screening. Previous studies demonstrate that newborns with QTc values over 470 msec of.. View More»
