Arrhythmia
Arrhythmias are abnormalities in the electrical activity of the heart. This can cause the heart to beat too fast, too slow, or irregularly. While arrhythmias are usually harmless, in some cases, they can be life-threatening.
Many different factors can contribute to arrhythmia. These include structural abnormalities in the heart, disorders of the heart’s electrical system, electrolyte imbalances, and underlying health conditions such as high blood pressure, diabetes, and sleep apnea.
Electrolytes are essential minerals in the blood to maintain normal heart function. When levels of electrolytes such as potassium and magnesium are low, it can lead to abnormal heart rhythms. For example, low potassium levels can cause tachycardia or a racing heart, while low magnesium levels can cause bradycardia or a slow heartbeat.
A study published in the American Journal of Cardiology found that patients with persistent atrial fibrillation, a type of irregular heartbeat, had lower magnesium levels than those without arrhythmias. The study’s authors conclude that magnesium replacement therapy may help to prevent or treat atrial fibrillation.
