Abstract
Long-QT syndrome(LQTS)is characterized by prolongation of ventricular repolar-ization time,and increase of inhomogeneity and dispersion.LQTS is dangerous because it may lead to torsade de pointes(TdP)and ventricular fibrillation.The clinical manifestations include syncope,tetany or sudden death.LQTS includes congenital long-QT syndrome(cLQTS)and ac-quired long-QT syndrome(aLQTS).The latter is more frequently seen in clinical practice than the former,and is potentially lethal,which makes it one of the most important reasons for sudden car-diac death in hospital.In the calculation of QT/QTc intervals,to evaluate ventricular repolariza-tion as accurately as possible in different methods within the recommended range of critical value of QT/QTc interval prolongation time can predict the occurrence of TdP and further reduce the rate of sudden death.关键词
