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 ...

Antiviral and anti-inflammatory drugs to combat COVID-19: Effects on cardiac ion channels and risk of ventricular arrhythmias [PDF]

BioImpacts, 2022
Introduction: Drugs with no indication for the treatment of cardiovascular diseases (e.g., drugs employed to treat COVID-19) can increase the risk of arrhythmias.

QT Interval Dynamics and Cardiovascular Outcomes: A Cohort Study in an Integrated Health Care Delivery System

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background Long QT has been associated with ventricular dysrhythmias, cardiovascular disease (CVD) mortality, and sudden cardiac death. However, no studies to date have investigated the dynamics of within‐person QT change over time in relation to risk of

QT interval dynamics in patients with ST-elevation MI

Frontiers in Cardiovascular Medicine, 2023
BackgroundAn association between excessively prolonged QT and ventricular arrhythmia in patients with ST-elevation myocardial infarction has been described; however, the QT dynamics, characterization, and long-term predictive value are not well known ...

Assessment of Severity of Long QT Syndrome Phenotype and Risk of Fetal Death

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background It has been postulated that long QT syndrome (LQTS) can cause fetal loss through putative adverse effects of the channelopathy on placenta and myometrial function.

Long QT in stunned myocardium: unrecognised cause of acquired long QT syndrome

Journal of Medical Science, 2014
Long QT syndrome (LQTS) is a heart disorder characterized by a prolongation of the QT interval on ECG and a predisposition to ventricular tachyarrhythmias, which may lead to syncope, cardiac arrest or sudden cardiac death. This condition may be inherited

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.
