Hyponatremia Presenting as Cardiac Conduction Defect.

ABSTRACT

Hyponatremia, the most common electrolyte disorder in hospitalized patients is usually asymptomatic. Clinical cardiac toxicity associated with hyponatremia has not been previously described, Although it is usually difficult to single out hyponatremia as the cause of conduction defects thus,we describe a case that developed reversible cardiac conduction defect temporally associated with hyponatremia.
