Abstract

Periodic paralysis associated with thyrotoxicosis is characterized by intermittent flaccid paralysis of the skeletal muscle. The paralysis usually involve the skeletal muscle of the limbs, especially lower extrimities. In general, sensory function is intact. Involvement of respiratory, ocular or bulbar muscles is very rare, but bulbar and respiratoy invelvement may prove fatal. It is very rare a case that has severe clinical manifestation such as cardiac arrest. We report a case of thyrotoxic hypokalemic periodic paralysis presenting as cardiac arrest.
