QT Interval in Pregnant and Non-pregnant Women

Archives of Academic Emergency Medicine, 2018
Introduction: Prolongation of QT interval might result in dangerous cardiac arrhythmias, including Torsades de Pointes (TdP), consequently leading to syncope or death.

Nomenclature, categorization and usage of formulae to adjust QT interval for heart rate.

World Journal of Cardiology, 2015
Assessment of the QT interval on a standard 12 lead electrocardiogram is of value in the recognition of a number of conditions. A critical part of its use is the adjustment for the effect of heart rate on QT interval. A systematic search was conducted to

QT interval in healthy dogs: which method of correcting the QT interval in dogs is appropriate for use in small animal clinics?

Pesquisa Veterinária Brasileira, 2014
The electrocardiography (ECG) QT interval is influenced by fluctuations in heart rate (HR) what may lead to misinterpretation of its length. Considering that alterations in QT interval length reflect abnormalities of the ventricular repolarisation which ...

Altered circadian rhythmicity of the QT interval predicts mortality in a large real-world academic hospital population

Heliyon
Objective 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:

Effects of Neostigmine and Sugammadex for Reversal of Neuromuscular Blockade on QT Dispersion Under Propofol Anesthesia: A Randomized Controlled Trial

Cardiology and Therapy, 2018
Introduction Reversal of non-depolarizing neuromuscular blocking agent neostigmine is associated with QT prolongation under general anesthesia. To clarify the effects of neostigmine and sugammadex on hemodynamic status, the QT interval and QT dispersion ...
