Andersen-Tawil syndrome (ATS) is a rare condition consisting of ventricular arrhythmias, periodic paralysis, and dysmorphic features. In 2001, mutations in KCNJ2, which encodes the α subunit of the potassium channel Kir2.1, were identified in patients ...

Abstract Background and Purpose Drug–drug interactions (DDIs) are associated with an increased risk of adverse drug reactions (ADRs). Hospitalized children are particularly vulnerable to DDIs and ADRs due to polypharmacy, frequent use of unlicensed or off‐label medications, and dosing regimens often extrapolated from adult data.

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.

Predictive Analytics for Identification of Patients at Risk for QT Interval Prolongation – A Systematic Review [PDF]
Prolongation of the heart rate‐corrected QT (QTc) interval increases the risk for torsades de pointes (TdP), a potentially fatal arrhythmia. The likelihood of TdP is higher in patients with risk factors, which include female sex, older age, heart failure

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

Blockage of some ion channels and in particular, the hERG cardiac potassium channel delays cardiac repolarization and can induce arrhythmia. In some cases it leads to a potentially life-threatening arrhythmia known as Torsade de Pointes (TdP).

On-chip constructive cell-network study (II): on-chip quasi-in vivo cardiac toxicity assay for ventricular tachycardia/fibrillation measurement using ring-shaped closed circuit microelectrode with lined-up cardiomyocyte cell network [PDF]
Backgrounds Conventional in vitro approach using human ether-a-go-go related gene (hERG) assay has been considered worldwide as the first screening assay for cardiac repolarization safety.

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.

. Congenital long QT syndrome (LQTS) is a life-threatening ion channelopathy caused by mutations in genes encoding specific ion channels, which can result in malignant arrhythmia of the torsades de pointes type.
