2. Antiarrhythmic agent - Wikipedia

   en.wikipedia.org/wiki/Antiarrhythmic_agent

   Amiodarone has mostly Class III activity, but also I, II, & IV activity [6] Prevent paroxysmal atrial fibrillation [7] and haemodynamically stable ventricular tachycardia [8] (amiodarone) Treat atrial flutter and atrial fibrillation (ibutilide) Treat ventricular tachycardia and atrial fibrillation (sotalol) Treat Wolff-Parkinson-White syndrome; IV

3. 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]

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. 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]

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. Cardioversion - Wikipedia

   en.wikipedia.org/wiki/Cardioversion

   Various antiarrhythmic agents can be used to return the heart to normal sinus rhythm. [3] Pharmacological cardioversion is an especially good option in patients with atrial fibrillation of recent onset. Drugs that are effective at maintaining normal rhythm after electric cardioversion can also be used for pharmacological cardioversion.

9. Arrhythmogenic cardiomyopathy - Wikipedia

   en.wikipedia.org/wiki/Arrhythmogenic_cardiomyopathy

   Pharmacologic management of ACM involves arrhythmia suppression and prevention of thrombus formation. 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 ...
