Prevalence of prolonged QTcinterval in electrocardiograms of 1 -12 year-old seizure patients [PDF]

, 2012
Background: Children with long QT intervals are prone to life-threatening ventricular arrhythmias which may lead to seizure and syncope and may be misdiagnosed as seizure.

Determination and Interpretation of the QT Interval: Comprehensive Analysis of a Large Cohort of Long QT Syndrome Patients and Controls

Circulation, 2018
Background: Long QT syndrome (LQTS) is associated with potentially fatal arrhythmias. Treatment is very effective, but its diagnosis may be challenging.

Spatiotemporal Transcriptomic Profiling Reveals the Dynamic Immunological Landscape of Alveolar Echinococcosis

Advanced Science, EarlyView.
An unprecedented high‐resolution spatial atlas of the E. multilocularis infection foci is obtained, revealing the dynamic functions of neutrophils, Spp1+ macrophages, and fibroblasts during disease progression. The transition of parasite control strategy from “active killing” to “negative segregation” by the host may provide instructive insights into ...

Vomiting, electrolyte disturbance, and medications; the perfect storm for acquired long QT syndrome and cardiac arrest: a case report

Journal of Medical Case Reports, 2022
Background Acquired long QT syndrome is an important and preventable cause of cardiac arrest. Certain medications and electrolyte disturbance are common contributors, and often coexist. In this case, we report five contributors to cardiac arrest.

Identification of a targeted and testable antiarrhythmic therapy for long-QT syndrome type 2 using a patient-specific cellular model

European Heart Journal, 2018
Aims Loss-of-function mutations in the hERG gene causes long-QT syndrome type 2 (LQT2), a condition associated with reduced IKr current. Four different mutation classes define the molecular mechanisms impairing hERG.

Treatement methodes for Long QT syndrome

Journal of Education, Health and Sport, 2018
Long QT syndrome (LQTS) is a potentially fatal cardiac disorder caused by channelopathies. Such arrhythmia is often life threatening and might cause sudden cardiac death. There are many reasons of LQTS especially: specific medications and/or electrolytes

Exploring the impact of a KCNH2 missense variant on Long QT syndrome: insights into a novel gender-selective, incomplete penetrance inheritance mode

Frontiers in Genetics
BackgroundLong QT syndrome (LQTS) is an inherited malignant arrhythmia syndrome that poses a risk of sudden death. Variants in the Potassium Voltage-Gated Channel Subfamily H Member 2 (KCNH2) gene are known to cause Long QT syndrome through an autosomal ...

Fluoxetine Treatment in Epilepsy of Infancy with Migrating Focal Seizures Due to KCNT1 Variants: An Open Label Study

Annals of Neurology, EarlyView.
Objective Gain‐of‐function (GoF) variants in KCNT1 encoding for potassium channels are associated with different epilepsy phenotypes, including epilepsy of infancy with migrating focal seizures (EIMFS), other early infantile developmental and epileptic encephalopathies, and focal epilepsy.

Molecular Pathophysiology of Congenital Long QT Syndrome.

Physiological Reviews, 2017
Ion channels represent the molecular entities that give rise to the cardiac action potential, the fundamental cellular electrical event in the heart. The concerted function of these channels leads to normal cyclical excitation and resultant contraction ...
