Long QT syndrome (LQTS) is a rare but highly arrhythmogenic cardiac disease characterized by an abnormally prolonged QT interval on the electrocardiogram (ECG)1. In the context of a prolonged QT, it is common to observe the appearance of Torsade de pointes (TdP) events1,2.TdPis a life-thre...

Results QTc interval was significantly ( P < 0.0002) (Table 1) lengthened 15 min after anaesthesia induction with sevoflurane as well as 60 min ( P < 0.01) after the ending of the gas exposition without any difference in age and gender. The QTc interval in patients anaesthetised with ...

least dependency of QTc on RR interval. Results: The following regression equations were obtained relating QT to RR: QT=2.4RR 0.72 , r 2 =0.79, with RR intervals varying between 210 and 350 ms. QTc lengthened significantly in all conscious rabbits given intravenous ...
scoring system (where 3 points ϭ an item indicat- ing greatest likelihood of LQTS, such as QTc Ն 480 millisec- onds; and 0.5 points ϭ an item indicating least likelihood, such as congenital deafness), based on personal and family history, symptomatology, and ECG has been developed...
