Magnesium Deficiency And Arrhythmias The Mineral Your Heart Rhythm Depends On
Magnesium deficiency is another causative factor of heart rhythm disturbances that is not paid enough attention. Although other body nutrients such potassium and calcium often get the limelight, magnesium is at the centre stage when it comes to maintaining a normal and robust heartbeat. The risk of arrhythmia irregular heartbeats may become extremely high when magnesium levels decrease.The linkage between magnesium deficiency and arrhythmias may help to ensure your cardiovascular well being and avoid harmful complications.
Importance Of Magnesium To Heart Rhythm
Magnesium is an Important mineral and plays a role in over 300 body biochemical reactions. Regulation of electrical signals in the heart is among one of its most important functions.
Your heart also beats as a result of the well managed electrical impulses. Magnesium helps:
Such electrical signals may become unstable in the absence of proper magnesium. The instability can cause arrhythmias like atrial fibrillation, premature ventricular contractions PVCs or worse still, arrhythmias may also result in more serious rhythm disorders.
The Effect Of Magnesium Deficiency On Arrhythmias
Magnesium has got a close association with other electrolytes, particularly, potassium. Potassium levels may also be hard to manage when the amount of magnesium is less. This disproportion interferes with the electrical activity of the heart.
Low magnesium hypomagnesemia may result in:
Heart palpitations
However, irregular or fast heartbeat.
Muscle cramps
Fatigue
Dizziness
More severely, magnesium deficiency can lead to having significant arrhythmias such as ventricular tachycardia or torsades de pointes, which is a potentially deadly arrhythmia.

The individuals who are at increased risk of magnesium deficiency are those who have:
Chronic stress
Type 2 diabetes
Gastrointestinal disorders
Heavy alcohol use
Long-term diuretic use
Poor dietary intake
The Relationship Between Magnesium And Atrial Fibrillation
Atrial fibrillation AFib, is one of the most common arrhythmias related to low magnesium. AFib is a condition in which the chambers of the heart above the atria beat at an irregular speed and out of phase with the chambers located beneath the heart.
Studies indicate that a normal level of magnesium may be useful in preventing the occurrence of AFib, particularly when one is undergoing heart surgery or when experiencing bouts of electrolyte imbalance. Magnesium can also be administered intravenously in hospitals to normalise life threatening heart rhythm.
Symptoms Of Possible Magnesium Deficiency
The deficiency of magnesium may be insidious. Early signs may include:
Anxiety or irritability
Poor sleep
Muscle twitching
Weakness
Headaches
With a further decrease in the levels, cardiovascular symptoms are likely to develop, such as palpitations or irregular heartbeat. Magnesium levels can be easily checked through a simple blood test it is worth mentioning, though, that most magnesium is stored within the cells and thus mild cases may not necessarily be evident through typical blood tests.
Healthy Dietary Sources Of Magnesium
The positive aspect is that the deficiency in magnesium can be easily avoided by diet. Foods that contain high levels of magnesium are:
Spinach leafy green, Swiss chard leafy green
Seeds, pumpkin seeds and almonds
Whole grains
Avocados
Black beans
Dark chocolate
In other cases, magnesium supplements can be prescribed. Nevertheless, supplementation is to be considered with a medical worker, particularly in the case of kidney disease or heart disorders. The simplest, but effective method of promoting the heart rhythm is the maintenance of optimal levels of magnesium. In case of regular palpitations or abnormal heartbeats, it can be worthwhile to check on your magnesium level.
Overall, the role of magnesium in the stability of electrical activity and cardiovascular exertion may not be given as much attention as other heart health nutritious components, but it constitutes a fundamental basis to cardiovascular and electrical activity operations. The proper intake will be ensured by either the diet or supplementary dietary means in case of need, this will reduce the risk of arrhythmias and will provide the heart with a steady, healthy beat. Speak with your medical professional to be properly tested and advised in case of the issue of magnesium deficiency or heart rhythm issues.
