Žurnal Grodnenskogo Gosudarstvennogo Medicinskogo Universiteta, 2019 Interpretation of each electrocardiogram should include measurement and evaluation of the QT interval, because both an increase and a decrease in its duration are associated with a risk of polymorphic ventricular tachycardia and sudden cardiac death ...

QT interval analysis in type 2 diabetic patients
مجلة كلية الطب, 2011 Background: The electrocardiographic QT interval has been extensively studied in diabetes mellitus. Recently, there has been increasing interest in the relationship between diabetes and QT abnormalities .The QT interval, which is easily obtained from a ...

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 ...

QTc evaluation in patients with bundle branch block
International Journal of Cardiology: Heart & Vasculature, 2020 Proper measurement of the QT interval on the 12-lead body-surface ECG is challenging in daily practice. Even more difficult is its correct estimation in the presence of repolarization abnormalities, arrhythmias or bundle-branch blocks (BBB).

Effect of age and gender on QT interval
National Journal of Physiology, Pharmacy and Pharmacology, 2018 Background: The sudden cardiac death syndrome has a large preponderance in men compared to women and that too in older age group. Various population studies have demonstrated four- to seven-fold increase of sudden cardiac death among men compared with ...

Recent heart rate history affects QT interval duration in atrial fibrillation. [PDF]
PLoS ONE, 2017 QT interval prolongation is associated with a risk of polymorphic ventricular tachycardia. QT interval shortens with increasing heart rate and correction for this effect is necessary for meaningful QT interval assessment.

EFFECT OF ANAESTHESIA ON THE QT INTERVAL [PDF]
British Journal of Anaesthesia, 1989 A prolonged electrocardiographic QT interval may be harmful during general anaesthesia. It may be prudent, therefore, to select anaesthetic agents which have the least effect on the QT interval. In a controlled study, propofol has been shown to have less effect on the QT interval than thiopentone (P less than 0.05).

Evaluation of differences in automated QT/QTc measurements between Fukuda Denshi and Nihon Koden systems. [PDF]
PLoS ONE, 2014 Automatic measurement becomes a preference, and indeed a necessity, when analyzing 1000 s of ECGs in the setting of either drug-inducing QT prolongation screening or genome-wide association studies of QT interval.

Sex and Rate Change Differences in QT/RR Hysteresis in Healthy Subjects
Frontiers in Physiology, 2022 While it is now well-understood that the extent of QT interval changes due to underlying heart rate differences (i.e., the QT/RR adaptation) needs to be distinguished from the speed with which the QT interval reacts to heart rate changes (i.e., the so ...
