Congenital Long QT Syndrome: a Systematic Review [PDF]

Acta Clinica Croatica, 2021
Congenital long QT syndrome (LQTS) is a disorder of myocardial repolarization defined by a prolonged QT interval on electrocardiogram (ECG) that can cause ventricular arrhythmias and lead to sudden cardiac death.

QT Adaptation and Intrinsic QT Variability in Congenital Long QT Syndrome [PDF]

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2015
Background Increased variability of QT interval (QTV) has been linked to arrhythmias in animal experiments and multiple clinical situations. Congenital long QT syndrome (LQTS), a pure repolarization disease, may provide important information on the ...

Congenital long QT syndrome [PDF]

Orphanet Journal of Rare Diseases, 2008
Congenital long QT syndrome (LQTS) is a hereditary cardiac disease characterized by a prolongation of the QT interval at basal ECG and by a high risk of life-threatening arrhythmias. Disease prevalence is estimated at close to 1 in 2,500 live births. The

Prevalence of the Congenital Long-QT Syndrome [PDF]

Circulation, 2009
Background— The prevalence of genetic arrhythmogenic diseases is unknown. For the long-QT syndrome (LQTS), figures ranging from 1:20 000 to 1:5000 were published, but none was based on actual data. Our objective was to define the prevalence of LQTS.

Genetic variant annotation scores in congenital long QT syndrome [PDF]

Annals of Noninvasive Electrocardiology, 2023
Background Congenital Long QT Syndrome (LQTS) is a hereditary arrhythmic disorder. We aimed to assess the performance of current genetic variant annotation scores among LQTS patients and their predictive impact.
