Final answer:
Amiodarone is a potassium channel blocker used as an antiarrhythmic infusion for stable wide-QRS tachycardia. The exact IV dosage should be determined by a healthcare provider in accordance with clinical guidelines.
Step-by-step explanation:
The question concerns the appropriate intravenous (IV) dosage of amiodarone, a potassium channel blocker antiarrhythmic medication used for the treatment of stable wide-QRS tachycardia. When considering the administration of amiodarone IV dose for antiarrhythmic infusion in stable wide-QRS tachycardia it is crucial to adhere to established clinical guidelines and consult with a healthcare provider for the most accurate dosing and administration protocol.
Amiodarone works by impeding the movement of K+ through voltage-gated K+ channels affecting the repolarization phase of the cardiac action potential. It is essential for healthcare professionals to monitor the patient's response to the drug and make any necessary adjustments to the dosage based on the clinical situation.
