Long QT Syndrome: a comprehensive review of the literature and current evidence

Long QT syndrome (LQT) represents a heterogeneous family of cardiac electrophysiologic disorders characterized by QT prolongation and T-wave abnormalities on the electrocardiogram. It is commonly associated with syncope, however, sudden cardiac death can occur due to torsades de pointes. LQT is a clinical diagnosis and should be suspected in individuals on the basis of clinical presentation, family history and ECG characteristics. Management is focused on the prevention of syncope and ultimately sudden death.
