Congenital Short QT Syndrome [PDF]

Indian Pacing and Electrophysiology Journal, 2004
Long QT intervals in the ECG have long been associated with sudden cardiac death. The congenital long QT syndrome was first described in individuals with structurally normal hearts in 1957.1 Little was known about the significance of a short QT ...

In Vitro Drug Screening Using iPSC-Derived Cardiomyocytes of a Long QT-Syndrome Patient Carrying KCNQ1 & TRPM4 Dual Mutation: An Experimental Personalized Treatment

Cells, 2022
Congenital long QT syndrome is a type of inherited cardiovascular disorder characterized by prolonged QT interval. Patient often suffer from syncopal episodes, electrocardiographic abnormalities and life-threatening arrhythmia.

Drug-induced Fatal Arrhythmias: Acquired long QT and Brugada Syndromes [PDF]

, 2017
Since the early 1990s, the concept of primary “inherited” arrhythmia syndromes or ion channelopathies has evolved rapidly as a result of revolutionary progresses made in molecular genetics.

Congenital long QT syndrome

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

Long QT syndrome in a neonate [PDF]

, 2015
Congenital long QT syndrome (cLQTS) is a channelopathy characterized by ventricular repolarization disturbances. The clinical presentation varies from an asymptomatic patient to a patient with recurrent syncopes, seizures, and even sudden death.

Meta-analysis of T peak –T end and T peak –T end /QT ratio for risk stratification in congenital long QT syndrome [PDF]

, 2018
Background and objectives: Congenital long QT syndrome (LQTS) predisposes affected individuals to ventricular tachycardia/fibrillation (VF/VF), potentially resulting in sudden cardiac death.

Long QT interval in resting electrocardiogram– and what next? Sports cardiologist’s point ofview Part 2. From provocative tests to prevention of cardiac events

Pediatria i Medycyna Rodzinna, 2014
Resting electrocardiogram is a basic diagnostic tool used to identify myocardial diseases caused by a genetic defect of ion channels that results in bioelectric instability of cardiomyocytes and the risk of a complex induction of life-threatening ...

The QT Intervals in Infancy and Time for Infantile ECG Screening for Long QT Syndrome [PDF]

, 2011
Background: Electrocardiographic and molecular studies have clarified an association between sudden infant death syndrome (SIDS) and long QT syndrome (LQTS), and few data are available for the QT interval in infancy from birth to 1 year of age ...
