In the treatment of cardiac arrhythmias of varying genesis, an “observational study” in 1,160 patients showed that a high-dose oral magnesium preparation (Magnesium-Diasporal N 300 Granulat) was effective. In 82% of the patients observed, a dose of at least 300 mg magnesium/day produced good to very good results.

Our results show that the therapeutic effect of intravenous magnesium is mainly on reducing the fast ventricular response rate in patients with acute onset atrial fibrillation. Its effectiveness and also the associated cardiovascular side effects are less significant than intravenous calcium antagonists or amiodarone.Does magnesium stop AFib?
Studies suggest magnesium supplements may also help lower blood pressure slightly. Other research has shown that getting magnesium through an IV may help control AFib for some people in the hospital.

Does magnesium cause muscle twitching?
Patients with low magnesium levels can develop muscle spasms, presumably because a deficiency in magnesium lowers the electrical threshold at which nerve cells become depolarized, which makes them hyper-excitable. The same is true for calcium, and low calcium levels can also cause muscle spasm.
