Comparison of Four Rate-Correction Algorisms for the Ventricular Repolarization Period in Assessing Net Effects of IKr Blockers in Dogs

Journal of Pharmacological Sciences, 2006
The utility of corrected and uncorrected QT interval changes for assessing net repolarization delay by IKr (a rapid component of delayed rectifier K+ currents) blockers was assessed in halothane-anesthetized dogs using the electrocardiogram and ...

Evaluation of Ventricular Repolarisation Features with Novel Electrocardiographic Parameters in Patients with Severe Periodontitis

İstanbul Medical Journal, 2020
Introduction:Ventricular arrhythmic predictors in severe periodontitis may be linked with cardiovascular events and the sudden death risk. In this study, we evaluated certain electrocardiographic (ECG) ventricular arrhythmic predictors in patients with ...

Methods of Assessment and Clinical Relevance of QT Dynamics [PDF]

, 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

Comprehensive translational assessment of human-induced pluripotent stem cell derived cardiomyocytes for evaluating drug-induced arrhythmias [PDF]

, 2016
Induced pluripotent stem cell-derived cardiomyocytes (iPSC-CM) hold promise for assessment of drug-induced arrhythmias and are being considered for use under the comprehensive in vitro proarrhythmia assay (CiPA).

Hyperpyrexia associated with congenital Long QT Syndrome

Çukurova Üniversitesi Tıp Fakültesi Dergisi, 2014
Congenital long QT syndrome (CLQTS) is a genetic disorder presented with prolonged QT interval. In these patients, risk of sudden cardiac death due to ventricular tachyarrhythmias is high.

THE WAYS TO ENHANCE SAFETY OF COMBINATIONS OF DRUGS PROLONGING QT INTERVAL IN THE OUT-PATIENT AND POLYCLINIC PRACTICE

Вестник анестезиологии и реаниматологии, 2018
Prolongation of QT interval is a predictor of fatal disorders of cardiac rhythm and sudden death. Side effects of medications is one of the main causes of prolonged QT interval.
