The hereditary long QT syndrome (LQT) is a disease characterized by lengthened ventricular repolarization, diagnosed by the presence of a prolongation of the QT interval on the electrocardiogram (ECG) (Fig. 9.1) and associated with sudden cardiac death (SCD). The prevalence of the disease is thought to be around 1/5,000 of the general population. While

Over the past half century, LQTS has matriculated through several critical milestones including its sentinel clinical description, clinical diagnostic scorecard, pathogenetic discovery, decade of research-based genetic testing and genotype–phenotype correlations, and clinical availability of genetic testing. In this chapter, we will discuss the history,

1. LQTS is a group of disorders characterized by abnormal cardiac ion channels resulting in a prolonged QT interval on ECG and leading to arrhythmias, particularly torsades de pointes (TdP), syncope, and sudden death. The characteristic finding on ECG is prolongation of the QT interval. (See Fig. 97.1) 2.

Hereditary long QT syndrome (LQTS) is a congenital disorder characterized by a prolongation of the QT interval detectable on the standard 12-leads ECG. The natural history of LQTS is characterized by the development of life-threatening ventricular arrhythmias as torsade de pointes (TdP).

Congenital and acquired long QT syndromes (CLQTS’s) have similar features and torsade de pointes is the arrhythmia they have in common. Such arrhythmia, generally self-limiting, can sometimes result in ventricular fibrillation and cause sudden death.
