Long QT syndrome. New electrocardiographic characteristics.
The long QT syndrome is electrocardiographically characterized by a prolonged QT interval and by several other, more subtle, ST-T-U wave abnormalities, most of which have not been quantified. To determine the possible usefulness of several new electrocardiographic characteristics in identifying patients with known long QT syndrome, logistic regression models were applied to a data base of seven...
متن کامل[New insights into the long-QT syndrome].
Long QT Syndrome (LQTS) is an arrhythmogenic disease in which prolongation of cardiac repolarization alters electrical stability of the heart predisposing affected individuals to cardiac arrest. The first arrhythmic manifestations occur during adolescence and largely are triggered by increased sympathetic activity. Mutations in genes encoding ion channels or ion channels’ controlling proteins h...
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...
