Intravenous Magnesium to help Reduce Cardiac Arrhythmias

intravenous magnesium IV nutrient therapy

Intravenous magnesium infusions help to deliver this powerful nutrient in a concentration that is not possible with just oral supplementation. The role magnesium has in our bodies is massive, it is part of over 300 enzymatic reactions and its role in supporting cardiac health has been studied over the last decade.

Magnesium has a unique effect on the conduction of electrical signals in the heart, where it can help to prevent and reduce symptoms of many common heart arrhythmias. In fact, giving intravenous magnesium post heart surgery appears to reduce the risk of atrial fibrillation and ventricular arrhythmia.

How does magnesium reduce heart arrhythmias?

The powerful agent reduces the repolarization of the sinus node, slowing down the heart rate. It also helps to reduce retrograde conduction (backwards flow of electrical current along the nerve fibres) that can occur with some arrhythmias. It also helps to synchronize the repolarization of both ventricles, rather than them working out of rhythm with each other.

Magnesium has many uses, including reducing symptoms of migraines, improving mood (reducing symptoms of anxiety or depression), and may also improve relaxation of tense muscles.
