Abstract
Thyrotoxic Periodic Paralysis is an uncommon disorder seen primarily in Asian males and caused by excessive thyroid hormones. This is an endocrine emergency that can lead to respiratory failure, dysrhythmia, and death. The mainstay of therapy has been potassium replacement, however, recent evidence suggests propranolol is a more effective therapy. We present a severe case of TPP in a 22-year-old Latino male with rapidly progressive ascending paralysis and hypokalemia severe enough to lead to cardiac arrest.
