QTc interval measurement in patients with right bundle branch block: A practical method

Annals of Noninvasive Electrocardiology, 2023
Background and Aim Prolonging the QT interval in the right bundle branch block (RBBB) can create challenges for electrophysiologists in estimating repolarization time and eliminating the effect of depolarization changes on QT interval.

The ketogenic diet and the QT interval [PDF]

Baylor University Medical Center Proceedings, 2019
Long QT syndrome is a disorder of ventricular myocardial repolarization associated with an increased risk of life-threatening cardiac arrhythmias and sudden cardiac death. This report highlights a case of QT prolongation with torsades de pointes in a patient with baseline congenital long QT syndrome, believed to be precipitated by metabolic changes ...

Meta-analysis of T peak –T end and T peak –T end /QT ratio for risk stratification in congenital long QT syndrome [PDF]

, 2018
Background and objectives: Congenital long QT syndrome (LQTS) predisposes affected individuals to ventricular tachycardia/fibrillation (VF/VF), potentially resulting in sudden cardiac death.
