The effects of peritoneal dialysis on QT interval in ESRD patients

BMC Nephrology, 2022
Background Patients with chronic kidney disease (CKD) are at a high risk of fatal arrhythmias. The extended corrected QT (QTc) interval is a hallmark of ventricular arrhythmias and sudden cardiac death.

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.

Utility of corrected QT interval in orthostatic intolerance. [PDF]

PLoS ONE, 2014
We performed this study to determine whether electrocardiographic corrected QT (QTc) interval predicts alterations in sympathovagal balance during orthostatic intolerance (OI).

The effect of esmolol on corrected-QT interval, corrected-QT interval dispersion changes seen during anesthesia induction in hypertensive patients taking an angiotensin-converting enzyme inhibitor

Revista Brasileira de Anestesiologia, 2015
BACKGROUND AND OBJECTIVES: The importance of minimizing the exaggerated sympatho-adrenergic responses and QT interval and QT interval dispersion changes that may develop due to laryngoscopy and tracheal

METHODOLOGICAL APPROACHES TO MEASURING AND ESTIMATING THE DURATION OF QT INTERVAL OF A STANDARD ELECTROCARDIOGRAM

Žurnal Grodnenskogo Gosudarstvennogo Medicinskogo Universiteta, 2019
Interpretation of each electrocardiogram should include measurement and evaluation of the QT interval, because both an increase and a decrease in its duration are associated with a risk of polymorphic ventricular tachycardia and sudden cardiac death ...

Can indicators of myocardial damage predict carbon monoxide poisoning outcomes?

BMC Emergency Medicine, 2021
Background Carbon monoxide causes electrical, functional, and morphological changes in the heart. It is unclear, however, whether the indicators of myocardial damage can predict the patient’s prognosis after carbon monoxide poisoning.

Increases of QT dispersion, corrected QT dispersion and QT interval in young healthy individuals during Ramadan fasting [PDF]

Acta Medica Iranica, 2003
Ramadan fasting is one of the most important religious duties of Muslims, that its effect on the heart has not been determined yet. Our objective was to evaluate the effect of Ramadan fasting on ventricular repolarization as assessed by QT interval ...

Electrocardiographic Changes Associated With Ibrutinib Exposure

Cancer Control, 2020
Although ibrutinib-associated atrial and ventricular arrhythmias have been well described, there is little information about ibrutinib’s effects on other electrocardiographic parameters, particularly the QT interval.

QTc interval on 24‐hour holter monitor: To trust or not to trust?

Annals of Noninvasive Electrocardiology, 2022
Introduction QT interval represents the ventricular depolarization and repolarization. Its accurate measurement is critical since prolonged QT can lead to sudden cardiac death.
