The aim of this prospective, longitudinal study was to determinate the distribution of QT interval in children practicing sport and to evaluate changes in QT duration overtime.D'Ascenzi, FlavinUniv SienaAnselmi, FrancescaUniv SienaGraziano, FrancescaBerti, BeatriceFranchini, AndreaBacci, ElodiCeccon, ...
QTc values for each formula were plotted against age and RR interval. Analysis of variance and regression analysis were used to compare the four formulae and the QT-RR relationship. RESULTS: Mean age was 17.7 weeks (range 4-72) and mean weight 6.3 kg (range 2.68-12.7). The QT-RR ...

We sought to determine whether the relationship between heart rate (HR) and QT interval (QT) differs as HR increases in response to exercise, atropine and isoproterenol. Background Autonomic nervous system influences on repolarization are poorly understood and may complicate the interpretation of QT ...
aWith ischaemia there is less shortening of the QT interval or even a prolongation during exercise . Therefore, normal values for QT interval-heart rate during ramp exercise tests on bicycles were required. Since generally, interval at rest is longer in women than in men both sexes were include...
Prolongation of the QT interval has been associated with increased vulnerability to ventricular arrhythmias and implicated as a mechanism for the Sudden Infant Death Syndrome (SIDS). Since QT prolongation may result from imbalance of the cardiac sympathe
