For which condition is a dosage of 300mg of Amiodarone (Cordarone) administered as IV push?

The administration of 300mg of Amiodarone as an IV push is indicated for ventricular fibrillation. Ventricular fibrillation is a life-threatening cardiac arrhythmia characterized by disorganized electrical activity in the ventricles, leading to ineffective heart contractions and cessation of blood flow. The acute treatment for this condition often includes advanced cardiac life support (ACLS) protocols, in which Amiodarone is utilized to stabilize the heart rhythm and restore effective circulation.

In this scenario, the high dose of 300mg is specifically indicated after an initial shock has been delivered during a cardiopulmonary resuscitation (CPR) attempt. This dosage is chosen for its rapid action in converting the chaotic electrical activity of ventricular fibrillation into a normal rhythm, making it an essential drug in emergency cardiac care. Other arrhythmias listed, such as stable ventricular tachycardia, atrial fibrillation, and supraventricular tachycardia, generally do not require such aggressive dosing or may be treated with different protocols and dosages.
