'''Antiarrhythmic agents''', also known as '''cardiac dysrhythmia medications''', are a class of [[drug]]s that are used to suppress abnormally fast rhythms ([[tachycardia]]s), such as [[atrial fibrillation]], [[supraventricular tachycardia]] and [[ventricular tachycardia]].

Many attempts have been made to classify antiarrhythmic agents. Many of the antiarrhythmic agents have multiple modes of action, which makes any classification imprecise.
