Dofetilide is a class III anti-arrhythmic drug that has been approved for the treatment of atrial fibrillation. Two clinical studies, which enrolled 996 patients, demonstrated pharmacological conversion to sinus rhythm to occur in 30% of patients. Following pharmacological or electrical

Drugs that block the cardiac K(+) channel encoded by the human ether-à-go-go gene (hERG) have been associated with QT interval prolongation leading to proarrhythmia, and in some cases, sudden cardiac death. Because of special structural features of the hERG K(+)

Dofetilide is a new, pure class III antiarrhythmic agent that prolongs the refractory period and action potential duration without having beta-blocking or calcium channel-blocking properties, making it unique among established class III agents. Dofetilide is effective in converting atrial and

The novel antiarrhythmic drug K201 (4-[3-{1-(4-benzyl)piperidinyl}propionyl]-7-methoxy-2,3,4,5-tetrahydro-1,4-benzothiazepine monohydrochloride) is currently in development for treatment of atrial fibrillation. K201 not only controls intracellular calcium release by the ryanodine receptors, but also possesses a ventricular action that might predispose to torsade de pointes

A number of predisposing factors have been suggested to be contributing to drug-induced torsade de pointes (TdP) arrhythmias: short-long-short (SLS) sequence, bradycardia, timing of drug administration, anaesthesia, ventricular remodelling, and altered ventricular activation due to ventricular ectopic beats (SLS) or
