Parálisis hipocalémica como manifestación de enfermedad de Graves.

Thyrotoxic periodic paralysis is an unusual complication of hyperthyroidism that frequently presents in a dramatic fashion, needing treatment in an emergency department or admission to an intensive care unit. It is characterized by recurrent episodes of flaccid muscle paralysis, hypokalemia and elevated levels of triiodothyronine (T3) and thyroxine (T4). Potassium supplementation and B-adrenergic blockers are essential in the prevention of cardiopulmonary complications, and the effective control of hyperthyroidism is indicated to prevent the recurrence of paralysis.
