women. According to anEmaxmodel,E0(milliseconds) was related to sex, δEmax(milliseconds) was related to ethnicity, and the EC50was 3.13μmol/l. The authors concluded that Korean subjects are less sensitive to quinidine-induced QT interval prolongation than Caucasian subjects, and that this trend...

1,2 Heart rate–corrected QT interval prolongation has long been established as an important risk factor for SCD, conveying a 2- to 3-fold increased risk in certain populations.3,4 As such, use of QT interval–prolonging medication (QTPM) has represented a traditional target for prevention ...

QT interval prolongation and decreased heart rate variability in cirrhotic patients: relevance of hepatic venous pressure gradient and serum calcium. A prolongation of QT interval has been shown in patients with cirrhosis and it is considered as part of the definition of the so-called ‘cirrhotic ca...
However, 25-30% of LQTS cases have a negative genetic test and LQTS genes do not adequately explain the heritability of the QT in the general population, or predisposition to QT-prolongation from precipitating factors such as medication8,9. Fig. 1: Annotation of an example ECG signal. QRS ...

Prolongation of the QT interval usually indicates delayed ventricular repolarization (i.e., prolongation of the QT segment) but may also reflect delayed depolarization (i.e., QRS prolongation). QT prolongation due to delayed repolarization may be congenital or acquired and predisposes to torsades de...
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...
