It delineates the nature of the algebraic dependence of QT as a function of R-R for the normal heart operating in the physiologic range that is consistent with basic physical principles and requires that the duration of diastole (TQ interval) as a function of HR be given by TQ = R-R ...
The normal duration of the QT interval varies with the heart rate (HR), thus several normalization formulas have been developed in order to compare QT interval values. Bazett's formula is the most commonly used: [QTc = QT/sqrt(R − R)]. QTc is the corrected QT interval, but it is ...

在QT中,quint和qint是Qt框架中定义的特定数据类型,用于处理无符号整数和有符号整数。如果需要将quint或qint转换为常规int,可以使用Qt提供的类型转换函数。 对于quint类型,可以使用qint64 quint::toLongLong()函数将其转换为常规的long long类型整数。然后,可以使用int qint64::toInt()函数将long long类型整数转...
Twenty-eight girls with Turner syndrome but only 2 controls had a rate-corrected QT interval above the reference range. We found no correlation between body habitus, cardiac dimensions, or metabolic parameters and the rate-corrected QT interval duration in girls with Turner syndrome. CONCLUSIONS....
