Irregular heartbeat

One of the most dangerous side effects of magnesium shortage is a heart arrhythmia or irregular heartbeat. Arrhythmia can happen in a variety of ways, from no symptoms to severe symptoms. It may cause heart palpitations in some people, which are pauses between heartbeats. Arrhythmia can also cause the following symptoms: lightheadedness, shortness of breath, chest pain, fainting, dizziness, and fatigue.

Arrhythmia can raise the risk of stroke or heart failure in the most severe cases. An imbalance of potassium levels within and outside of heart muscle cells, a disease linked to magnesium deficiency, is thought to be to blame, according to scientists. Magnesium levels have been shown to be lower in patients with congestive heart failure and arrhythmia than in people who do not have heart failure. Magnesium injections significantly improved heart function in 68 patients with heart failure in a small study. Magnesium supplements may also benefit some people with arrhythmia symptoms.
