Genetics of acquired long QT syndrome.
The QT interval is the electrocardiographic manifestation of ventricular repolarization, is variable under physiologic conditions, and is measurably prolonged by many drugs. Rarely, however, individuals with normal base-line intervals may display exaggerated QT interval prolongation, and the potentially fatal polymorphic ventricular tachycardia torsade de pointes, with drugs or other environmen...

Here, KCNE1 and KCNE2 variants are studied among Iranian affected families with this syndrome. Materials and Methods: Fifty patients referring to Rajaei Cardiov...
متن کاملLong QT Syndrome
Background. Erythromycin is known to prolong ventricular repolarization and has been associated with the occurrence of torsades de pointes. In this study, we have investigated potential mechanisms in vivo and in vitro for induction of an acquired long QT syndrome by erythromycin. Methods and Results. Ventricular electrograms and endocardial monophasic action potentials were recorded in anesthet...
متن کاملThe Long QT Syndrome
Introduction The Long QT syndrome (LQTS) can be inherited or acquired and is of particular interest and concern at present. Patients with LQTS are predisposed to the ventricular tachyarrhythmia torsade de pointes (TdP) which causes syncope and sudden death. Inherited LQTS is the prototype of the "primary cardiac arrhythmias" or "cardiac ion channelopathies". The study of inherited LQTS has prov...
