2. Amiodarone - Wikipedia

   en.wikipedia.org/wiki/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]

3. 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. Many attempts have been made to classify antiarrhythmic agents.

4. Potassium channel blocker - Wikipedia

   en.wikipedia.org/wiki/Potassium_channel_blocker

   Amiodarone is also safe to use in individuals with cardiomyopathy and atrial fibrillation, to maintain normal sinus rhythm. Amiodarone prolongation of the action potential is uniform over a wide range of heart rates, so this drug does not have reverse use-dependent action. Amiodarone was the first agent described in this class. [4]

5. Atrial flutter - Wikipedia

   en.wikipedia.org/wiki/Atrial_flutter

   Immediate treatment of atrial flutter centers on slowing the heart rate with medications such as beta blockers (e.g., metoprolol) or calcium channel blockers (e.g., diltiazem) if the affected person is not having chest pain, has not lost consciousness, and if their blood pressure is normal (known as stable atrial flutter).

6. Ibutilide - Wikipedia

   en.wikipedia.org/wiki/Ibutilide

   Ibutilide is a Class III antiarrhythmic agent that is indicated for acute cardioconversion of atrial fibrillation and atrial flutter of a recent onset to sinus rhythm. It exerts its antiarrhythmic effect by induction of slow inward sodium current, which prolongs action potential and refractory period of myocardial cells.

7. Supraventricular tachycardia - Wikipedia

   en.wikipedia.org/wiki/Supraventricular_tachycardia

   Some atrial tachycardias, rather than being a result of increased automaticity may be a result of a micro-reentrant circuit (defined by some as less than 2 cm in longest diameter to distinguish it from macro-reentrant atrial flutter). Still other atrial tachycardias may be due to triggered activity caused by after-depolarizations. [19]

8. AV nodal reentrant tachycardia - Wikipedia

   en.wikipedia.org/wiki/AV_nodal_reentrant_tachycardia

   The main symptom of AVNRT is the sudden development of rapid regular palpitations. [1] These palpitations may be associated with a fluttering sensation in the neck, caused by near-simultaneous contraction of the atria and ventricles against a closed tricuspid valve leading to the pressure or atrial contraction being transmitted backwards into the venous system. [2]

9. Cardioversion - Wikipedia

   en.wikipedia.org/wiki/Cardioversion

   Drugs that are effective at maintaining normal rhythm after electric cardioversion can also be used for pharmacological cardioversion. Drugs like amiodarone, diltiazem, verapamil and metoprolol are frequently given before electrical cardioversion to decrease the heart rate, stabilize the patient and increase the chance that cardioversion is ...
