In Wikidata. 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.
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. [3][4] Disopyramide has a negative inotropic effect on the ventricular myocardium, significantly decreasing the ...
Antiarrhythmic. Sodium channel blockers are used in the treatment of cardiac arrhythmia. They are classified as "Type I" in the Vaughan Williams classification. Class I antiarrhythmic agents interfere with the (Na +) channel. Class I agents are grouped by their effect on the Na + channel, and by their effect on cardiac action potentials.
Amiodarone. Amiodarone is an antiarrhythmic medication used to treat and prevent a number of types of cardiac dysrhythmias. [4] This includes ventricular tachycardia, ventricular fibrillation, and wide complex tachycardia, atrial fibrillation, and paroxysmal supraventricular tachycardia. [4] Evidence in cardiac arrest, however, is poor. [5]
Flecainide is a class Ic antiarrhythmic agent. [1] It works by decreasing the entry of sodium in heart cells, causing prolongation of the cardiac action potential. [1] Flecainide was approved for medical use in the United States in 1985. [1] It is available as a generic medication. [3]
Procainamide. Procainamide (PCA) is a medication of the antiarrhythmic class used for the treatment of cardiac arrhythmias. It is a sodium channel blocker of cardiomyocytes; thus it is classified by the Vaughan Williams classification system as class Ia.
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.
Quinidine. Quinidine is a class IA antiarrhythmic agent used to treat heart rhythm disturbances. [1] It is a diastereomer of antimalarial agent quinine, [2] originally derived from the bark of the cinchona tree. The drug causes increased action potential duration, as well as a prolonged QT interval.
