Amiodarone is preferred in which condition according to Vaughan Williams Classification?

  1. Heart Failure

  2. Atrial Fibrillation

  3. Supraventricular arrhythmias

  4. Ventricular arrhythmias

The correct answer is: Heart Failure

According to Vaughan Williams Classification, Amiodarone, a medication used to treat irregular heartbeats, is most commonly preferred for patients with Heart Failure. Although it may also be used for other conditions, such as Atrial Fibrillation (irregular heartbeat in the upper chambers of the heart), Supraventricular arrhythmias (irregular heartbeats in the upper chambers of the heart), and Ventricular arrhythmias (irregular heartbeats in the lower chambers of the heart), it is primarily preferred for treating Heart Failure due to its effectiveness in regulating the heart's rhythm and reducing the risk of further complications. Therefore, options B, C, and D are incorrect because Amiodarone is not the first choice medication for those particular conditions according to Vaughan Williams Classification.
