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

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.

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.

Sex and Rate Change Differences in QT/RR Hysteresis in Healthy Subjects
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 ...

Measurement and interpretation of electrocardiographic QT intervals in murine hearts. [PDF]
Alterations in ECG QT intervals correlate with the risk of potentially fatal arrhythmias, for which transgenic murine hearts are becoming increasingly useful experimental models. However, QT intervals are poorly defined in murine ECGs.

Evaluation of differences in automated QT/QTc measurements between Fukuda Denshi and Nihon Koden systems. [PDF]
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.

Bedaquiline Correlation to QT Interval Prolongation in DR-TB Patients
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
