Measurement and interpretation of electrocardiographic QT intervals in murine hearts. [PDF]

, 2014
Alterations in ECG QT intervals correlate with the risk of potentially fatal arrhythmias, for which transgenic murine hearts are becoming increasingly useful experimental models. However, QT intervals are poorly defined in murine ECGs.

Corrected QT interval and QT dispersion in temporal lobe epilepsy

The Egyptian Journal of Neurology, Psychiatry and Neurosurgery, 2021
Background Cardiac arrhythmias are expected among patients with epilepsy due to the effect of anti-epileptic drugs. Temporal lobe epilepsy also causes autonomic seizures that may affect heart rhythm.

Long QT syndrome and torsades de pointes complicating mitral valve replacement

Indian Heart Journal, 2016
Severe QT interval prolongation >500 ms occurs in one quarter of cardiac surgical patients in the perioperative period while moderate prolongation occurs in most of them. Prolonged QT interval may be associated with torsades de pointes and lead to sudden

QT PRODACT: In Vivo QT Assay With a Conscious Monkey for Assessment of the Potential for Drug-Induced QT Interval Prolongation

Journal of Pharmacological Sciences, 2005
In safety pharmacology studies, the effects on the QT interval of electrocardiograms are routinely assessed using a telemetry system in cynomolgus monkeys. However, there is a lack of integrated databases concerning in vivo QT assays in conscious monkeys.

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.

Abnormal ECG Findings in Athletes: Clinical Evaluation and Considerations. [PDF]

, 2019
PURPOSE OF REVIEW: Pre-participation cardiovascular evaluation with electrocardiography is normal practice for most sporting bodies. Awareness about sudden cardiac death in athletes and recognizing how screening can help identify vulnerable athletes have
