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 ...

The Measurement of the QT Interval [PDF]

Current Cardiology Reviews, 2014
The evaluation of every electrocardiogram should also include an effort to interpret the QT interval to assess the risk of malignant arrhythmias and sudden death associated with an aberrant QT interval.

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:

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

Corrected QT interval and QT dispersion in temporal lobe epilepsy

The Egyptian Journal of Neurology, Psychiatry and Neurosurgery, 2021
Background Cardiac arrhythmias are expected among patients with epilepsy due to the effect of anti-epileptic drugs. Temporal lobe epilepsy also causes autonomic seizures that may affect heart rhythm.
