  2. Potassium channel blocker - Wikipedia

    en.wikipedia.org/wiki/Potassium_channel_blocker

    Sotalol is indicated for the treatment of atrial or ventricular tachyarrhythmias, and AV re-entrant arrhythmias. Ibutilide is the only antiarrhythmic agent currently approved by the Food and Drug Administration for acute conversion of atrial fibrillation to sinus rhythm. Azimilide; Bretylium; Clofilium; E-4031; Nifekalant [6] Tedisamil; Sematilide

  3. Bretylium - Wikipedia

    en.wikipedia.org/wiki/Bretylium

    The dose is 5–10 mg/kg and side effects are high blood pressure followed by low blood pressure and ventricular ectopy. Originally introduced in 1959 for the treatment of hypertension. [2] Its use as an antiarrhythmic for ventricular fibrillation was discovered and patented by Marvin Bacaner in 1969 at the University of Minnesota. [3]

  4. Ventricular fibrillation - Wikipedia

    en.wikipedia.org/wiki/Ventricular_fibrillation

    Ventricular fibrillation (V-fib or VF) is an abnormal heart rhythm in which the ventricles of the heart quiver. [2] It is due to disorganized electrical activity. [2] Ventricular fibrillation results in cardiac arrest with loss of consciousness and no pulse. [1] This is followed by sudden cardiac death in the absence of treatment. [2]

  5. Defibrillation - Wikipedia

    en.wikipedia.org/wiki/Defibrillation

    Defibrillation is a treatment for life-threatening cardiac arrhythmias, specifically ventricular fibrillation (V-Fib) and non-perfusing ventricular tachycardia (V-Tach). [1] [2] A defibrillator delivers a dose of electric current (often called a counter-shock) to the heart.

  6. Antiarrhythmic agent - Wikipedia

    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.

  7. Cardioversion - Wikipedia

    en.wikipedia.org/wiki/Cardioversion

    It is also used in the emergent treatment of wide complex tachycardias, including ventricular tachycardia, when a pulse is present. Pulseless ventricular tachycardia and ventricular fibrillation are treated with unsynchronized shocks referred to as defibrillation.

  8. Flecainide - Wikipedia

    en.wikipedia.org/wiki/Flecainide

    Flecainide is a medication used to prevent and treat abnormally fast heart rates. [1] This includes ventricular and supraventricular tachycardias. [1] Its use is only recommended in those with dangerous arrhythmias or when significant symptoms cannot be managed with other treatments. [1] Its use does not decrease a person's risk of death. [1]

    Anticoagulants: To prevent embolization.. Beta blockers: To block the effects of certain hormones on the heart to slow the heart rate.. Calcium Channel Blockers: Help slow the heart rate by blocking the number of electrical impulses that pass through the AV node into the lower heart chambers (ventricles).
