Cardiac manifestation of normokalemic periodic paralysis in 21 years old male in Kermanshah

Abstract

Background: Normokalemic periodic paralysis is an autosomal dominant disorder involving the abnormal function of skeletal muscle’s voltage-gated alpha-subunits. It is characterized by paralysis attack of varying severity with concomitant normal serum potassium concentration. Although normokalemic periodic paralysis is well established in the literature, but its cardiac manifestations are very rare.
