coronary artery vasospasm was observed on coronary angio-gram. Thyroid function testing revealed severe hyperthyroid-ism with a diagnosis of type 2 amiodarone-induced thyrotox-icosis (AIT) subsequently made. Treatment with prednisolone therapy was commenced and thyroid function rapidly nor-malized. Prednisolone was weaned without recurrence of hy-perthyroidism and on last review, 6 months after initial pre-sentation, he remains free from further chest pain and ar-rhythmias. Our patient’s presentation is a very rare case of AIT-associated coronary artery spasm and documented isch-aemic ventricular fibrillation with fortunate survival
