在临床工作中为了消除心率变化对QT间期的影响,从而提出了经心率校正之后的QT间期(Corrected QT interval , QTc)这一概念。 目前最常用的计算QTc的公式为Bazett提出的方程,即 QTc = QT / RR 1/2 。 Bazett’s方程有一定的适用范围,即当心率为50～90次/分时,经该方...

Conclusions As calculation of QTc dispersion is affected by sinus arrhythmia, which is common in childhood, we suggest that QT dispersion should not be corrected for heart rate in children.HAnkaraErcanAnkaraTutarAnkaraBAnkara?calAnkaraAAnkara
However, there is no universal formula for QTc calculation in dogs, and each laboratory should have its own formula, based on the analysis of data obtained from the strain used in its own experimental conditions.doi:10.1080/105172301300055133...

Many noncardiovascular drugs have the adverse effect to delay cardiac repolarization, a phenomenon that can be quantified in humans on the surface electrocardiogram (ECG) by the QT interval (1,2). Despite a number of limitations associated with its assessment, the drug-induced prolongation of QT ...

的QT间期值。目前最常用的QTc计算公式为Bazett方程,即QTc=QT/RR 1/2 。 后续研究发现该公式存在一定的适用范围,当心率过快或过慢时经该公式校正 的QTc值误差较大,之后又有多位学者提出多种QTc校正公式,但受到研究方 法及观察人群的限制,也都存在着这样或那样的不足,且计算公式较为复杂, ...
