QTc evaluation in patients with bundle branch block
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).

Increases of QT dispersion, corrected QT dispersion and QT interval in young healthy individuals during Ramadan fasting [PDF]
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 ...

A genome-wide association scan of RR and QT interval duration in 3 European genetically isolated populations:the EUROSPAN project [PDF]
We set out to identify common genetic determinants of the length of the RR and QT intervals in 2325 individuals from isolated European populations.We analyzed the heart rate at rest, measured as the RR interval, and the length of the corrected QT ...

QT interval has been determined in 103 monozygotic (MZ) and 198 dizygotic (DZ) female twins. Mean values of corrected QT (QTc) were almost identical for both groups at 413 ms (MZ) and 412 ms (DZ). There was a significant age and environmental effect on QT interval. Heritability explained about 25% of the variation in QT.

QT Interval Changes in Moderate and Severe Brain Injuries [PDF]
Backgrounds: Traumatic brain injuries are common mortality causes in many countries. Electrocardiogram (ECG) changes after brain injuries are known, and among them alteration of QT interval is common.

Recent heart rate history affects QT interval duration in atrial fibrillation. [PDF]
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.
