Atrial fibrillation (AF) is the most common cardiac arrhythmia. Mortality, and especially morbidity caused by AF, are major and growing health problems in the western world. AF is strongly associated with arterial hypertension, congestive heart failure, valvular heart disease, ischaemic

Expert opinion on investigational drugs, 9(11), 2695-2704 (2000-11-04)
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(+)

The Canadian journal of cardiology, 17(1), 63-67 (2001-02-15)
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
