Prevalence of Long QT Syndrome in Children with Congenital Sensory-Neural Deafness

Journal of Ardabil University of Medical Sciences, 2021
Background & objectives: Long QT syndrome (LQTS), congenital or acquired disorder, is characterized by a prolonged QT interval associated with syncope attacks and sudden death.

Screening for QT Prolongation in the Emergency Department: Is There a Better “Rule of Thumb?” [PDF]

, 2020
Introduction: Identification of QT prolongation in the emergency department (ED) is critical for appropriate monitoring, disposition, and treatment of patients at risk for torsades de pointes (TdP).

Momentum and Hamiltonian in Complex Action Theory

, 2012
In the complex action theory (CAT) we explicitly examine how the momentum and Hamiltonian are defined from the Feynman path integral (FPI) point of view based on the complex coordinate formalism of our foregoing paper.

T-wave alternans in long QT syndrome

Annals of Pediatric Cardiology, 2018
Long QT syndrome (LQTS) is a congenital disorder characterized by prolongation of QT interval in the electrocardiogram (ECG) and a propensity to develop ventricular arrhythmias, which may lead to syncope, cardiac arrest or sudden death. T-wave alternans (

Outcome by Sex in Patients With Long QT Syndrome With an Implantable Cardioverter Defibrillator

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Sex differences in outcome have been reported in patients with congenital long QT syndrome. We aimed to report on the incidence of time‐dependent life‐threatening events in male and female patients with long QT syndrome with an implantable ...

Finite dimensional attractor for a composite system of wave/plate equations with localised damping [PDF]

, 2010
The long-term behaviour of solutions to a model for acoustic-structure interactions is addressed; the system is comprised of coupled semilinear wave (3D) and plate equations with nonlinear damping and critical sources.

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 ...

The Clinical Utility of Continuous QT Interval Monitoring in Patients Admitted With COVID-19 Compared With Standard of Care: A Prospective Cohort Study

CJC Open, 2020
Background: QT interval monitoring has gained much interest during the COVID-19 pandemic because of the use of QT-prolonging medications and the concern about viral transmission with serial electrocardiograms (ECGs).

Smoluchowski-Kramers approximation in the case of variable friction

, 2012
We consider the small mass asymptotics (Smoluchowski-Kramers approximation) for the Langevin equation with a variable friction coefficient. The limit of the solution in the classical sense does not exist in this case.

Ion-specificity in {\alpha}-helical folding kinetics

, 2010
The influence of the salts KCl, NaCl, and NaI at molar concentrations on the {\alpha}-helical folding kinetics of the alanine-based oligopeptide Ace-AEAAAKEAAAKA-Nme is investigated by means of (explicit-water) molecular dynamics simulations and a ...
