Inherited Arrhythmias: Long QT Syndrome

The Challenge
Long QT syndrome (LQTS) is a disorder of cardiac repolarization. It is characterized by a prolongation of the QT interval, and a predisposition to ventricular tachyarrhythmias, which are associated with syncope, arrhythmic events, and sudden cardiac death (SCD). In recent years, there have been significant advances in understanding the genetic basis of the syndrome. Newer genetic forms of LQTS have been identified, too, plus a laboratory test has become available to help in the diagnosis of the syndrome. As knowledge of LQTS continues to expand, clinical applications of this growing body of information need further study
