Why the study?
Are QT and JT dispersion intervals increased in children with long QT syndrome compared to normal controls?
Are QT and JT dispersion intervals increased in children with long QT syndrome compared to normal controls?
QT and JT dispersion are significantly increased in children with long QT syndrome, and values ≥55 msec may help stratify risk for critical ventricular arrhythmias.
