Abstract

Hyperkalemic periodic paralysis is a channelopathy skeletal muscle that is characterized by recurrent episodes of muscle weakness that may be triggered by exercise, cold, rest or shortly after exercise and potassium intake.

We describe the case of a four-year-old girl with a family history of hyperkalemic periodic paralysis and an episode of weakness in legs. Asymptomatic until about six months before. Concern about three episodes of muscle weakness and numbness of legs at night, which resolve spontaneously in a few minutes. No other associated symptoms.
