It increases action potential duration and effective refractory period without impacting conduction velocity. These actions of dofetilide are explained by its ability to inhibit the rapid component of the delayed, outward-rectifying potassium current, thus blocking the efflux of potassium during repolarization. Introductory investigations suggest that dofetilide may be of use in treating and preventing atrial dysrhythmias such as atrial fibrillation, atrial flutter, and paroxysmal supraventricular tachycardia. Dofetilide may also have a role in preventing ventricular tachycardia from occurring. Some data also suggest that dofetilide may improve the morbidity of heart failure patients. Currently, the most troublesome adverse effect of dofetilide is its propensity to induce ventricular proarrhythmias, especially torsade de pointes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS:<\/jats:title>\n                    <jats:p>Based on the data currently available, dofetilide should have a role in the pharmacotherapy of cardiac dysrhythmias, especially those of atrial origin. More data on its efficacy and tolerability are needed, however, to fully delineate dofetilide's role amid currently available antiarrhythmic agents.<\/jats:p>\n
