Effect of QT interval-prolonging drugs taken in pregnancy on the neonatal QT interval [PDF]
Frontiers in Pharmacology, 2023 Introduction: Acquired QT interval prolongations due to drug side effects can result in detrimental arrhythmia. Maternal use of placenta-permeable drugs may lead to fetal exposure, thus leading to an increased risk of neonatal QT prolongation and ...

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).

Methods of Assessment and Clinical Relevance of QT Dynamics [PDF]
Indian Pacing and Electrophysiology Journal, 2005 The dependence on heart rate of the QT interval has been investigated for many years and several mathematical formulae have been proposed to describe the QT interval/heart rate (or QT interval/RR interval) relationship. While the most popular is Bazett’s

Congenital Short QT Syndrome [PDF]
Indian Pacing and Electrophysiology Journal, 2004 Long QT intervals in the ECG have long been associated with sudden cardiac death. The congenital long QT syndrome was first described in individuals with structurally normal hearts in 1957.1 Little was known about the significance of a short QT ...

Altered circadian rhythmicity of the QT interval predicts mortality in a large real-world academic hospital population [PDF]
HeliyonObjective and rationale: Small studies have shown that the QT interval follows a circadian rhythm. This finding has never been confirmed in a large real-world hospital population and the clinical meaning of disrupted rhythmicity remains unknown. Methods:
