title: Refractory cardiac arrhythmia due to hypomagnesmia.
abstract: A case of ventricular bigeminy possibly due to magnesium deficiency is reported. Magnesium sulphate was successfully used for its management. Differential diagnosis of idiopathic cardiac arrhythmias should always include hypomagnesemia as one of the causes and magnesium should be replaced for its proper management.
