QT Interval Changes in Moderate and Severe Brain Injuries [PDF]
, 2012 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]
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.

Heritability of Tpeak-Tend interval and T-wave amplitude: a twin study [PDF]
, 2011 Background— Tpeak-Tend interval (TpTe) and T-wave amplitude (Tamp) carry diagnostic and prognostic information regarding cardiac morbidity and mortality. Heart rate and QT interval are known to be heritable traits.

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 ...

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

A genome-wide association scan of RR and QT interval duration in 3 European genetically isolated populations:the EUROSPAN project [PDF]
, 2009 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 ...

Common Genetic Variation Near the Phospholamban Gene Is Associated with Cardiac Repolarisation: Meta-Analysis of Three Genome-Wide Association Studies [PDF]
, 2012 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 ...

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.
