Which medication requires monitoring every 3-6 months for thyroid function when used to treat arrhythmias?

Digoxin
Warfarin
Amiodarone
Propafenone

The correct answer is: Amiodarone

Amiodarone is the correct answer because it is known to cause thyroid dysfunction, including hypothyroidism and hyperthyroidism. Therefore, monitoring of thyroid function every 3-6 months is essential to detect any abnormalities early and adjust treatment as needed. Digoxin, Warfarin, and Propafenone do not typically require thyroid function monitoring as part of their routine monitoring parameters for the treatment of arrhythmias.
