Pharmacological β-adrenoceptor blockade can augment torsadogenic action of IKr inhibitor: Comparison of proarrhythmic effects of d-sotalol and dl-sotalol in the chronic atrioventricular block dogs

Journal of Pharmacological Sciences, 2019
Information is still limited whether β-blockade may augment or attenuate the onset of torsade de pointes in patients with IKr inhibitor-induced labile repolarization process.

Torsade de Pointes Following Myocarditis; A Case Report

Sakarya Tıp Dergisi, 2019
Myocarditis is defined as myocardial edema associated with non-ischemic necrosis in myocardial tissue. Acute viral myocarditis may cause several electrocardiographic changes. These include conduction disturbances, disorders of repolarization, ventricular

Intravenous anti-influenza drug oseltamivir will not induce torsade de pointes: Evidences from proarrhythmia model and action-potential assay

Journal of Pharmacological Sciences, 2016
We evaluated proarrhythmic risk of intravenous oseltamivir with chronic atrioventricular block canine model (n = 4) and action-potential assay on guinea-pig right ventricle (n = 5). Oseltamivir in doses of 3–30 mg/kg, i.v.

Analysis of torsadogenic and pharmacokinetic profile of E-4031 in dogs bridging the gap of information between in vitro proarrhythmia assay and clinical observation in human subjects

Journal of Pharmacological Sciences, 2018
We analyzed torsadogenic and pharmacokinetic profile of E-4031 using chronic atrioventricular block dogs. E-4031 in intravenous doses of 0.03, 0.1 and 0.3 mg/kg over 10 min prolonged QT/QTc, and increased short-term variability of QT in a dose-related ...

Predictive Value of Tpeak – Tend Indices for Adverse Outcomes in Acquired QT Prolongation: A Meta-Analysis

Frontiers in Physiology, 2018
Background: Acquired QT interval prolongation has been linked with malignant ventricular arrhythmias, such as torsade de pointes, in turn predisposing to sudden cardiac death. Increased dispersion of repolarization has been identified as a pro-arrhythmic
