5‐hydroxytryptamine type 3 (5‐HT3) receptor antagonists are used to treat nausea and vomiting and in the prevention of chemotherapy‐induced, radiation‐induced, and postoperative nausea and vomiting. Most of the 5‐HT3 receptor antagonists (i.e., ondansetron, tropisetron, dolasetron, palonosetron, and ramosetron) are metabolized by CYP2D6, but the extent

Facilitation of I Kr current by some hERG channel blockers suppresses early afterdepolarizations. [PDF]
Drug-induced block of the cardiac rapid delayed rectifying potassium current (I Kr), carried by the human ether-a-go-go-related gene (hERG) channel, is the most common cause of acquired long QT syndrome.

Evaluasi Elektrokardiogram Interval QTc dan JTc pada Penderita Malaria Vivaks yang Diberikan Dihidroartemisinin-Piperakuin dan Primakuin [PDF]
Dihidroartemisinin-piperakuin (DHA-PPQ) telah digunakan secara global sebagai terapi malaria vivaks. Salah satu efek samping DHA-PPQ adalah pemanjangan repolarisasi ventrikel yang dapat menimbulkanaritmia ventrikuler yaitu Torsade de Pointes (TdP). Studi

Exercising electrocardiograms from Thoroughbred racehorses with exercise associated sudden death
Abstract Background Exercise associated sudden death (EASD), defined as a fatal collapse in a closely monitored and previously presumed clinically healthy horse that occurs during exercise or within approximately 1 h after exercise, is disproportionately more common in equine than in human athletes.

Spatial patterns of excitation at tissue and whole organ level due to early afterdepolarizations [PDF]
Early after depolarizations (EAD) occur in many pathological conditions, such as congenital or acquired channelopathies, drug induced arrhythmias, and several other situations that are associated with increased arrhythmogenicity. In this paper we present

Jervell and Lange‐Nielsen Syndrome Related Clinical Genetics and Experimental Models
ABSTRACT Jervell and Lange‐Nielsen syndrome (JLNS) is defined by electrocardiographic QT prolongation and sensorineural hearing loss, caused by homozygous or compound heterozygous variants in KCNQ1 and/or KCNE1. KCNQ1 encodes the alpha subunit Kv7.1 of the ion channels accountable for slow delayed rectifier potassium currents (IKs), whereas KCNE1 ...

Torsade de pointes associated with encephalitis
Torsade de pointes is a polymorphic ventricular tachycardia. Causes of torsade de pointes are well described. Although intracranial disease can produce dramatic electrocardiographic (ECG) changes, we are not aware of previous cases with torsade de

Abstract Background and Purpose Between‐cell differences in ventricular cardiomyocyte action potential duration (APD) and responses to ion channel block may contribute to pro‐arrhythmic dispersion of myocardial repolarisation. This study quantifies between‐cell physiological and pharmacological variability in the rabbit left ventricle (LV) and uses ...

Drugs and life-threatening ventricular arrhythmia risk: results from the DARE study cohort. [PDF]
OBJECTIVES: To establish a unique sample of proarrhythmia cases, determine the characteristics of cases and estimate the contribution of individual drugs to the incidence of proarrhythmia within these cases.
