Hypokalaemia Re-Visited: A Case Series

Abstract

Hypokalaemia is a relatively common biochemical abnormality found at the emergency department. Sequential changes in the electrocardiogram occur as the serum potassium is lowered. Correction of hypokalaemia can be life-saving. It is essential for physicians to be able to recognise these changes and initiate prompt replacement when necessary. We present a case series of patients presenting to the emergency department with symptomatic hypokalaemia and discuss the electrocardiographic manifestations and recognition of hypokalaemic changes.
