    en.wikipedia.org/wiki/Antiarrhythmic_agent

    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.

    en.wikipedia.org/wiki/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. As of 2019, its IV formulation is no longer being ...

  5. Potassium channel blocker - Wikipedia

    en.wikipedia.org/wiki/Potassium_channel_blocker

    Effect of class III antiarrhythmic agent on cardiac action potential. Potassium channel blockers used in the treatment of cardiac arrhythmia are classified as class III antiarrhythmic agents. Atrial cardiomyocytes contain a specific subset of potassium ion channels which are absent in the ventricles. [ 1 ]

  6. Sodium channel blocker - Wikipedia

    en.wikipedia.org/wiki/Sodium_channel_blocker

    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. Class I agents are ...

    It may be used in pregnancy, but has not been well studied in this population. [3] [4] Use is not recommended in those with structural heart disease or ischemic heart disease. [1] 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]

  8. Lorcainide - Wikipedia

    Lorcainide (Lorcainide hydrochloride) is a Class 1c antiarrhythmic agent that is used to help restore normal heart rhythm and conduction in patients with premature ventricular contractions, ventricular tachycardiac [1] and Wolff–Parkinson–White syndrome. [2]

  9. Arrhythmogenic cardiomyopathy - Wikipedia

    en.wikipedia.org/wiki/Arrhythmogenic_cardiomyopathy

    Sotalol, a beta blocker and a class III antiarrhythmic agent, is the most effective antiarrhythmic agent in ACM. Other antiarrhythmic agents used include amiodarone and conventional beta blockers (i.e.: metoprolol). If antiarrhythmic agents are used, their efficacy should be guided by series ambulatory Holter monitoring, to show a reduction in ...
