Antiarrhythmic agents, also known as cardiac dysrhythmia medications, are a class of drugs that are used to suppress abnormally fast rhythms (tachycardias), such as atrial fibrillation, supraventricular tachycardia and ventricular tachycardia. Many attempts have been made to classify antiarrhythmic agents.
The following are medications commonly prescribed cardiac pharmaceutical agents. The specificity of the following medications is highly variable, and often are not particularly specific to a given class. As such, they are listed as are commonly accepted.
Disopyramide (INN, trade names Norpace and Rythmodan) is an antiarrhythmic medication used in the treatment of ventricular tachycardia. [2] It is a sodium channel blocker and is classified as a Class 1a anti-arrhythmic agent.
Representation of the ion channel opening/closing that antiarrhythmics act upon . Antiarrhythmics are broad class of drugs that are used treat heart rhythm irregularities. [16] Utilizing the Vaughan-Williams (VW) system, antiarrhymic drugs are classified into four main classes based on their mechanism of action. Class I antiarrhymics lead to ...

Of the sodium channel blocking antiarrhythmic agents (the class I antiarrhythmic agents), the class Ic agents have the most potent sodium channel blocking effects. Class Ic agents are indicated for supraventricular arrhythmias (i.e. atrial fibrillation) and as a last line treatment for refractory life-threatening ventricular tachycardia or ...
