Key result
Radioiodine therapy for hyperthyroidism linked to rare thyroid storm and complete heart block.
Why the study?
Thyroid storm is a rare endocrine emergency that can be precipitated by radioiodine therapy and may be accompanied by life-threatening bradycardia, a rare complication.
Case Report (n=1)
Highlights a rare but life-threatening complication of complete heart block and bradycardia accompanying thyroid storm precipitated by radioiodine therapy.
May prompt cardiac monitoring after radioiodine; extends rare thyroid storm reports but leaves open incidence and prevention strategies.
Thyroid storm is a rare endocrine emergency characterized by dysfunction of multiple organ systems. Thyroid storm is more common in Graves' disease and can be precipitated by surgery, trauma, infection, metabolic abnormalities, iodine load, and parturition. We present a diagnostically challenging case of thyroid storm precipitated by radioiodine therapy and accompanied by bradycardia, a rare but life-threatening complication related to treatment for hyperthyroidism.

Vennard et al. (2018) conducted a case report in Thyroid storm and complete heart block (n=1). Radioiodine therapy was evaluated on Thyroid storm and bradycardia. Radioiodine therapy for hyperthyroidism precipitated a rare and life-threatening case of thyroid storm accompanied by bradycardia and complete heart block.
