Analyzing repolarization patterns in pediatric population with congenital heart disease

As prolonged QT is suggestive of a myocardium that is at risk of ventricular arrhythmia, a cross-sectional study published in the journal of Pediatric Cardiology assessed the repolarization patterns in children with cyanotic and acyanotic congenital heart diseases. It was observed that prolonged QTc was higher in children with acyanotic congenital heart diseases with volume overload and increased left ventricular end diastolic dimension was a significant association. Moreover, reduced oxygen saturation was a significant association.
