87- A 70 year old male was receiving amiodarone 200 mg daily for intermittent atrial fibrillation. However, he was aware of tiredness and lethargy. He appeared clinically euthyroid with no palpable goitre.
Investigations revealed:
Serum free T4 23pmol/L (9-26)
Serum total T3 0.8 nmol/L (0.9-2.8)
Serum TSH 8.2 mU/L (<5)
Which of the following statements would explain these results?
