title: [New antiarrhythmic drugs for atrial fibrillation].
abstract: The development of new antiarrhythmic drugs is mainly aimed to treat atrial fibrillation, because of its prevalence and major consequences in terms cerebral vascular thrombosis. Specific blockade of I(Na) et I(K), even if efficacious, have previously shown to be proarrhythmogenic, with a global impairment of the cardiac patient's outcome. This lead to the development of new drugs, selectively targeting atrial currents such as I(Kur) ou I(KAch). The efficacy of amiodarone in treatment of atrial fibrillation has also yielded a whole array of new antiarrhythmic drugs targeting both these atrial currents but also sharing amiodarone pharmacodynamics properties. This renders the Vaughan-Williams classification ill-adapted for such drugs.
