Effect of QT interval-prolonging drugs taken in pregnancy on the neonatal QT interval [PDF]

Frontiers in Pharmacology, 2023
Introduction: Acquired QT interval prolongations due to drug side effects can result in detrimental arrhythmia. Maternal use of placenta-permeable drugs may lead to fetal exposure, thus leading to an increased risk of neonatal QT prolongation and ...

Methods of Assessment and Clinical Relevance of QT Dynamics [PDF]

Indian Pacing and Electrophysiology Journal, 2005
The dependence on heart rate of the QT interval has been investigated for many years and several mathematical formulae have been proposed to describe the QT interval/heart rate (or QT interval/RR interval) relationship. While the most popular is Bazett’s

Pharmacogenetics of Drug-Induced QT Interval Prolongation: An Update [PDF]

Drug Safety, 2015
A prolonged QT interval is an important risk factor for ventricular arrhythmias and sudden cardiac death. QT prolongation can be caused by drugs. There are multiple risk factors for drug-induced QT prolongation, including genetic variation.

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 ...

Prevalence of the QT interval prolongation and its risk factors in hospitalized geriatric patients: findings of a single center cross-sectional study in Pakistan [PDF]

BMC Geriatrics
Background and objectives Geriatric inpatients are particularly susceptible to Torsades de Pointes (TdP) because they are usually polymorbid and often take QT-prolonging drugs.

Altered circadian rhythmicity of the QT interval predicts mortality in a large real-world academic hospital population [PDF]

Heliyon
Objective and rationale: Small studies have shown that the QT interval follows a circadian rhythm. This finding has never been confirmed in a large real-world hospital population and the clinical meaning of disrupted rhythmicity remains unknown. Methods:

A Study on the Diurnal Variation of Ventricular Repolarization Parameters in Patients with Obstructive Sleep Apnea [PDF]

Zhongguo quanke yixue, 2022
BackgroundObstructive sleep apnea hypopnea syndrome (OSAHS) is a common sleep breathing disorder. More and more studies have shown that OSAHS has a significant correlation with cardiovascular disease.

Genetic analyses of the electrocardiographic QT interval and its components identify additional loci and pathways

Nature Communications, 2022
The QT interval is an electrocardiographic measure representing the sum of ventricular depolarization and repolarization, estimated by QRS duration and JT interval, respectively. QT interval abnormalities are associated with potentially fatal ventricular

Serial electrocardiogram recordings revealed a high prevalence of QT interval prolongation in patients with tuberculosis receiving fluoroquinolones

Journal of the Formosan Medical Association, 2023
Background: Fluoroquinolones, crucial components of treatment regimens for drug-resistant tuberculosis (TB), are associated with QT interval prolongation and risks of fatal cardiac arrhythmias. However, few studies have explored dynamic changes in the QT
