Brief summary

This is a double-blind, placebo-controlled trial of oral magnesium in patients suffering from paroxysmal atrial fibrillation. The aim of this study is to investigate the effect of oral magnesium on the incidence of paroxysmal lone atrial fibrillation. In order to do this participants will be randomised to oral magnesium or placebo. The participants’ incidence of atrial fibrillation will be monitored for a 12 month period to determine whether oral magnesium reduces the number of episodes of atrial fibrillation.

Interventions

One oral tablet of Herron Magnesium Plus taken twice daily for 1 year following randomisation. Herron Magnesium Plus contains: Magnesium Oxide (Magnesium 320mg) 530.7mg Manganese sulfate monohydrate (Manganese 5mg) 15.4mg Pyridoxine hydrochloride (vitamin B6) 50mg
