Abstract The congenital long QT syndromes are a heterogeneous group of disorders that are characterized by prolongation of the QT interval on the 12-lead electrocardiogram, episodes of syncope, ventricular arrhythmias such as torsades de pointes and a high incidence of sudden death.

The clinical phenotype of the long QT syndrome (LQTS) is quite variable, with the frequency and type of life-threatening arrhythmias influenced by the specific genotype and a spectrum of genetic and environmental factors that are not well characterized.

Long QT syndrome and anaesthesia
European Journal of Anaesthesiology, 2002The long QT syndrome is a disorder of myocardial electrical conduction that leaves the heart vulnerable to the ventricular tachydysrhythmia torsade de pointes. Clinically, this results in syncope or sudden death. The long QT syndrome may be congenital, if caused by abnormal myocardial potassium or sodium ion channels, or acquired, if due to drugs ...

The long QT syndrome (LQTS) is a congenital disorder characterized by a prolongation of the QT interval on electrocardiogram and a propensity to ventricular tachyarrhythmias, which may lead to cardiac events defined as syncope, cardiac arrest, or sudden death. Children are very frequently affected by LQTS accounting for about 50% of probands and 40% to

Significance of QT dispersion in the long QT syndrome
Progress in Cardiovascular Diseases, 2000The long QT syndrome (LQTS) has often been considered as a model to study the abnormalities of cardiac repolarization in humans because it represents a pure electrical disease with no evidence of cardiac structural abnormalities. The arrhythmogenic potential of prolonged ventricular repolarization has been extensively studied both in experimental ...

The long QT syndrome (LQTS) is a genetically transmitted cardiac arrhythmia due to ion channel protein abnormalities, which affects the transport of potassium and sodium ions across the cell membrane. Patients with LQTS may present with syncope, seizures or aborted cardiac arrest.

Congenital long QT syndrome (LQTS) is an inherited arrhythmia syndrome characterized by a prolonged QT interval in the 12-lead ECG, torsades de pointes and not negligible prevalence of sudden cardiac death. The genetic testing plays an important role in the diagnosis of LQTS. A total of 15 genes have been reported for autosomal-dominant forms of Romano-

The so-called congenital long QT syndrome (LQTS) is an inherited arrhythmia syndrome predisposing to life-threatening ventricular arrhythmias and sudden death. It is caused by prolongation of the repolarization phase of the cardiac action potential, which may manifest as lengthening of the heart rate-corrected QT interval (QTc) on the surface ...

Figure 1. A two-year-old boy came to medical attention because he lost consciousness four times over a period of five months. Three of the episodes occurred when the child became upset. These episodes had previously been diagnosed as “breath-holding spells.” He was also found to have severe sensorineural hearing loss. The child was taking no medication.

A young woman with a history of seizure disorder and depression suffered a syncopal event. Her ECG revealed QTc prolongation, which resolved with discontinuation of QTc prolonging medications. After experiencing a recurrent syncopal episode, an implantable loop recorder revealed Torsade de pointe.
