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 ...

QT Interval and QT Variability [PDF]
, 2012 Sudden cardiac death (SCD) is among the most common types of mortality in developed countries. It for more deaths each year than the total number of deaths from AIDS, breast cancer, lung cancer and stroke together. SCD accounts for approximately 50% of all deaths from cardiovascular diseases and 20% of total mortality (1).

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).

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.

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 ...

Circulation: Arrhythmia and Electrophysiology, 2019 BACKGROUND Long QT syndrome is a potentially lethal yet highly treatable cardiac channelopathy. Although β-blocker therapy is standard for most patients, concomitant therapy with sodium channel blockers, like mexiletine, is often utilized for patients ...

Bedaquiline Correlation to QT Interval Prolongation in DR-TB Patients
Jurnal Respirasi, 2022 Introduction: The regimen of drug-resistant tuberculosis (DR-TB) is Bedaquiline. One of the adverse events is QT interval prolongation, which can increase the risk of Torsade de Pointes (TdP) and lead to death. DR-TB patient screening before starting the
