Changes in the corrected QT interval and corrected QT dispersion during haemodialysis [PDF]

open access: yesPostgraduate Medical Journal, 2002
Abstract The link between increased QT dispersion and cardiac death in subjects with diabetes and arterial disease is well recognised. Corrected QT dispersion was studied in subjects with end stage renal failure on haemodialysis. Thirty one stable, chronic subjects on haemodialysis had 12-lead electrocardiograms (ECGs) taken before and ...

Novel genes for QTc interval. How much heritability is explained, and how much is left to find? [PDF]

open access: yes, 2010
The corrected QT (QTc) interval is a complex quantitative trait, believed to be influenced by several genetic and environmental factors. It is a strong prognostic indicator of cardiovascular mortality in patients with and without cardiac disease.

A Combination of Heart Rate-Corrected QT Interval and GRACE Risk Score Better Predict Early Mortality in Patients with Non-ST Segment Elevation Acute Coronary Syndrome

open access: yes, 2022
Objective: This study aimed to evaluate whether the addition of heart rate-corrected QT interval prolongation to the Global Registry of Acute Coronary Events risk score improves the predictive value for early mortality in patients with non-ST segment ...

Common Genetic Variation Near the Phospholamban Gene Is Associated with Cardiac Repolarisation: Meta-Analysis of Three Genome-Wide Association Studies [PDF]

open access: yes, 2009
To identify loci affecting the electrocardiographic QT interval, a measure of cardiac repolarisation associated with risk of ventricular arrhythmias and sudden cardiac death, we conducted a meta-analysis of three genome-wide association studies (GWAS ...

[QT Interval and Its Prolongation - What Does It Mean?] [PDF]

open access: yes, 2020
The assessment of the QT interval has been an integral part of ECG interpretation since the first descriptions of long QT syndrome by Wolff in 1950 and by Jervell and Lange-Nielsen in 1957.

Can indicators of myocardial damage predict carbon monoxide poisoning outcomes?

open access: yesBMC Emergency Medicine, 2021
Background Carbon monoxide causes electrical, functional, and morphological changes in the heart. It is unclear, however, whether the indicators of myocardial damage can predict the patient’s prognosis after carbon monoxide poisoning.

Correction of the QT Interval in Children.

open access: yesJapanese Circulation Journal, 1995
We evaluated the usefulness of 11 formulas for correcting the QT interval in children, including the square root, cubic root, logarithmic, linear, exponential, and inverse formulas using the Mean-squared residual (MSR) values and Akaike Information Criterion (AIC) in 8,086 first-graders, 9,989 seventh-graders, and 5,786 tenth-graders. The subjects were

Antipsychotics and Torsadogenic Risk: Signals Emerging from the US FDA Adverse Event Reporting System Database [PDF]

open access: yes, 2013
Background: Drug-induced torsades de pointes (TdP) and related clinical entities represent a current regulatory and clinical burden. Objective: As part of the FP7 ARITMO (Arrhythmogenic Potential of Drugs) project, we explored the publicly available US ...

Corrected QT Interval Prolongation in Hospitalized Pediatric Patients Receiving Methadone [PDF]

open access: yes, 2018
OBJECTIVES: Methadone is often used in pediatric patients to prevent or treat opioid withdrawal after prolonged sedation. Prolonged corrected QT interval is an important adverse effect of methadone because it can progress to torsades de pointes, a ...

A randomized controlled trial of the short-term effect of rosuvastatin on the corrected QT interval. [PDF]

open access: yesSci Rep
Rosuvastatin can block human ether-a-go-go related gene (hERG) currents and prolong the corrected QT (QTc) interval, but this effect has not been confirmed in the population.
