Manual vs. automatic assessment of the QT-interval and corrected QT [PDF]
Europace, 2023 Abstract Aims Sudden cardiac death (SCD) is challenging to predict. Electrocardiogram (ECG)-derived heart rate-corrected QT-interval (QTc) is used for SCD-risk assessment. QTc is preferably determined manually, but vendor-provided automatic results from ECG recorders are convenient.

Increases of QT dispersion, corrected QT dispersion and QT interval in young healthy individuals during Ramadan fasting [PDF]
Acta Medica Iranica, 2003 Ramadan fasting is one of the most important religious duties of Muslims, that its effect on the heart has not been determined yet. Our objective was to evaluate the effect of Ramadan fasting on ventricular repolarization as assessed by QT interval ...

The QT and Corrected QT Interval in Recovery After Exercise in Children [PDF]
Circulation: Arrhythmia and Electrophysiology, 2011 Background— Prolongation of the QT interval after exercise can be used to help diagnose long-QT syndrome, especially when the resting QT interval is borderline. The aim of this study was to determine the normal ranges for QT and corrected QT in the recovery phase after exercise in children ...

Corrected qt interval in normal egyptian neonates: Comparison to corrected qt interval of other ethnic groups [PDF]
Journal of the Saudi Heart Association, 2013 Long QT syndromes (LQTs) is a familial cardiovascular disorder characterized by abnormal cardiac repolarization and sudden death from ventricular fibrillation Possible acquisition of standardized neonatal screening method to identify children with (LQTs) has led to interest in establishing normal values for neonatal QT intervals.Aim of the workto ...

Turkish Journal of Science, 2019 Objective: The goal of this search was to find out whether the sensitivity of QT interval, QT dispersion (QTd), corrected QT interval (QTc) and corrected QT dispersion (QTcd) sensitivity in the early diagnosis of ventricular arrhythmia and cardiovascular mortality in normotensive obese children exists or not and to evaluate their relation with the ...

Corrected QT Interval in Children With Brain Death [PDF]
Pediatric Cardiology, 2010 Prolongation of the QT interval is a well-documented finding in adults with severe brain injury. However, QT prolongation has not been well documented in the pediatric population with brain injury. Our objective was to determine the range of QT intervals in children with the diagnosis of brain death, hypothesizing that the QT interval corrected for ...

Heart Rhythm, 2017 Long QT syndrome (LQTS) is characterized by reduced penetrance and variable QT prolongation over time, resulting in an estimate of 25% carriers of a pathogenic mutation with a normal corrected QT (QTc) interval on the resting electrocardiogram (ECG).The purpose of this study was to test the hypothesis that an individualized corrected QT interval ...

Automated versus Manual Measurement of the QT Interval and Corrected QT Interval [PDF]
Annals of Noninvasive Electrocardiology, 2011 Background: The International Conference on Harmonization E14 Guideline specifies detailed assessment of QT interval or corrected QT interval prolongation when developing new drugs. We recently devised new software to precisely measure the QT interval.
