Ventricular tachycardia associated with hereditary magnesium-losing nephropathy

Ventricular tachycardia (VT) can be a life threatening condition which can be caused by an underlying electrolyte disturbance, such as hypomagnesaemia. Causes of electrolyte disturbances, such as magnesium losing nephropathy, should be identified early to allow correct management of the underlying cause of the cardiac arrhythmia.
