Drug induced QT prolongation: the measurement and assessment of the QT interval in clinical practice.
There has been an increasing focus on drug induced QT prolongation including research on drug development and QT prolongation, following the removal of drugs due to torsades de pointes (TdP). Although this has improved our understanding of drug-induced QT prolongation there has been much less research aimed at helping clinicians assess risk in individual patients with drug induced QT prolongati...

Copyright © 2004 Massachusetts Medical Society. n the past decade, the single most common cause of the withdrawal or restriction of the use of drugs that have already been marketed has been the prolongation of the QT interval associated with polymorphic ventricular tachycardia, or torsade de pointes (Fig. 1), which can be fatal. 1 Nine structurally unrelated drugs...

متن کاملChanges in QT interval before and after hemodialysis
Background: Cardiovascular mortality and morbidity are high in chronic renal failure (CRF) patients. Increased dispersion of QT intervals is known to predispose to ventricular arrhythmias and sudden cardiac death. This study was conducted to assess the effect of hemodialysis (HD) on corrected QT (QTc) intervals and their dispersions (QTd) in chronic hemodialyzed patients. Methods: Fifty-eight p...
متن کاملPredicting drug-induced changes in QT interval and arrhythmias: QT-shortening drugs point to gaps in the ICHS7B Guidelines
BACKGROUND AND PURPOSE The regulatory guidelines (ICHS7B) recommending inhibition of the delayed rectifier K(+) current (I(Kr)), carried by human ether-a-go-go-related gene (hERG) channels in cardiac cells (the hERG test), as a 'first line' test for identifying compounds inducing QT prolongation, have limitations, some of which are outlined here. EXPERIMENTAL APPROACH hERG current was measure...
