Magnesium and Ventricular Arrhythmias: Is There a Relationship?
Arrhythmias are heart conditions that can be caused by an irregular heartbeat.
The atria and the ventricles are the upper and lower chambers of the heart. If you have an irregular heartbeat, you can either slow or speed up your heart rate.
An arrhythmia can lead to a premature beat.
Ventricular arrhythmias are the ones that happen in your heart’s lower chambers. There are two main types of ventricular arrhythmias, according to the
Ventricular Tachycardia is the first and means that your ventricles beat faster but often. The second type of ventricular tachycardia can be more severe and last more than a few seconds. Ventricular fibrillation can cause death.
Magnesium plays a role in keeping a steady heart rhythm, according to the
You may be wondering if magnesium can help manage these conditions. The article looks at the role of magnesium in arrhythmias.
Magnesium is in charge of heart muscle contraction, which means it helps keep your heart beating.
A typical heartbeat is maintained by multiple electrolytes like sodium, potassium, and calcium. Yet, magnesium is the nutrient responsible for regulating the movement of these electrolytes within the heart’s tissues.
If or when these electrolytes cannot function as they should, it can lead to irregular heartbeat, or arrhythmia.
In fact, studies show that up to 38% of people with ventricular arrhythmia have a magnesium deficiency, and 72% have excessive magnesium losses.
- acting as a calcium antagonist (meaning that it restricts the amount of calcium that enters the heart cells, allowing the heart to beat more slowly)
- “Increasing the cell’s energy levels.”
- Oxygen usage is improved.
- Reducing the release of neurotransmitters that speed up your heart rate is a way to do this.
A 2018 analysis of 22 studies evaluating the relationship between magnesium sulfate supplementation and arrhythmias found that magnesium may reduce the risk of ventricular and supraventricular arrhythmias by
Research from 2017 suggests that magnesium may have beneficial effects in treating drug-induced ventricular arrhythmias.
It’s important to note that magnesium supplements are not the main treatment for all ventricular arrhythmias. Usually, these conditions are managed with medications and, at times, defibrillation or intravenous (IV) lidocaine, an anesthetic.
However, IV magnesium is the first line treatment for those experiencing a specific type of ventricular tachyarrhythmia called Torsade de Pointes, as long as they have a pulse.
Magnesium may help with Torsade de Pointes, even in people whose magnesium levels are not considered low or deficient, but there
Magnesium is a mineral that’s abundantly present in your body and can be easily found in numerous foods and supplements, according to
It is involved in a wide range of bodily functions. It is necessary for heart health because of its role in nerve impulse conduction and muscle contraction.
According to the Food and Drug Administration (FDA), magnesium’s daily value (DV) is
However, research suggests that many Western-style eating patterns are low in this mineral. In fact,
Magnesium is available in many foods.
- Pumpkin and chia seeds are popular.
- There are nuts and beans.
- There is a vegetable called spinach.
- It is rice.
Evidence from 2016 suggests that your body can absorb up to 76% of dietary magnesium.
Still, common causes of low magnesium levels include:
- low intake of food.
- The bowel is removed during surgery.
- Decreases in GI function through vomiting or diarrhea.
- Drugs like lysergic acid diethylamide, lysergic acid diethylamide, and lysergic acid diethylamide are used for certain purposes.

Despite magnesium’s widely explored beneficial effects for ventricular arrhythmias, research from 2016 also reports a lack of consensus on dosage.
Excessive magnesium intake can lead to symptoms like diarrhea, nausea, and abdominal pain. Per
- low blood pressure.
- urine retention
- Weakness in the muscles.
- Difficult breathing
Some people may have an irregular heartbeat due to magnesium toxicity.
While magnesium supplements are generally well tolerated, they can also

There are a number of additional recommendations you could follow to improve or manage heart health.
For starters, according to 2015 guidelines from the European Society of Cardiology, you should be mindful of other electrolytes like potassium to reduce the risk of high blood pressure. High doses of potassium-sparing diuretics are common in people with heart failure.
Aim to follow a heart-healthy diet and exercise regularly to maintain a weight that’s healthy for you, which may help reduce other risk factors for heart disease, such as high blood cholesterol levels or high blood pressure.
Reducing the use of substances that can contribute to an irregular heartbeat is one way to do that.
Maintaining optimal magnesium levels is important.
Finally, the AHA recently added good sleep hygiene to the list of lifestyle factors that support cardiovascular health. Consider avoiding habits and substances that can compromise sleep quality, and make rest a priority when possible.
Ventricular arrhythmias are a potentially life threatening condition in which your heart beats too fast.
They are usually treated with a combination of drugs and procedures.
If the person has a pulse, they can be treated with IV magnesium even if they are not low or deficient in magnesium.
Research shows that magnesium deficiency increases the risk of ventricular arrhythmias.
Magnesium can help prevent and reduce ventricular arrhythmias, as well as address other risk factors for heart disease.
There is no consensus on the proper amount of magnesium and it can cause negative side effects. Talk with a healthcare professional before trying magnesium supplements.
You could prevent and manage ventricular arrhythmias by following a heart-healthy diet, exercising, and managing stress.
