Probucol-induced QT prolongation and torsades de pointes.
Probucol administration of 4 weeks produced torsades de pointes associated with exacerbated QT interval prolongation in a 36-year-old woman with Romano-Ward syndrome. With discontinuance of probucol, the QT interval corrected for rate shortened from 620 msec to 500 msec and ventricular ectopic beats disappeared completely. Although probucol is known to prolong the QT interval, associated ventri...
متن کاملDrug induced QT prolongation.
The drug-induced QT prolongation predisposes to development of torsades de pointes (TdP) ventricular tachycardia and sudden death. The association between specific drug and development of TdP is difficult to document, therefore, QT prolongation is considered as a surrogate marker of the proarrhythmia risk. Most of the drugs prolong QT interval usually by blocking the potassium IKr current or al...

Background: Although QT prolongation is associated with increased risk of torsade de pointes (TdP), the precise relationship is not well defined. Aim: To evaluate the performance of a QT nomogram in assessing the risk of TdP from QT– RR combinations. Design: Systematic review. Methods: We systematically searched MEDLINE/ EMBASE for cases of drug-induced TdP. Controls were patients taking non-ca...
