Area of Science:

  • Endocrinology
  • Cardiology

Background:

  • Thyroid storm, a severe form of thyrotoxicosis, presents diagnostic challenges, particularly in its apathetic variant.
  • Atypical clinical manifestations can obscure the diagnosis, delaying critical intervention.

Observation:

  • A 16-year-old female presented with fever, jaundice, heart failure, and complete heart block.
  • These unusual symptoms initially masked the underlying thyroid storm.

Findings:

  • Thyrotoxicosis-induced complete atrioventricular block is rare.
  • Prompt treatment with carbimazole, intravenous iodide, and dexamethasone led to the resolution of the conduction abnormality.

Implications:

  • This case underscores the importance of considering thyroid storm in patients with unexplained heart block, even with atypical presentations.
