Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Magnesium is commonly used in the management of certain cardiac arrhythmias, including heart fibrillation (such as atrial fibrillation) and palpitations. There is scientific validation for its use, especially in the hospital setting. Magnesium plays a crucial physiological role in cardiac conduction and muscle contraction. Deficiency in magnesium can predispose individuals to arrhythmias. Several studies, including randomized controlled trials, have shown that intravenous magnesium can be effective in the acute management of specific arrhythmias, such as torsades de pointes (a form of ventricular tachycardia) and for rate control in atrial fibrillation, particularly when associated with electrolyte imbalances. Clinical guidelines, including those from the American Heart Association, recommend magnesium supplementation in cases of documented hypomagnesemia and certain arrhythmias. Oral magnesium is sometimes suggested for palpitations when a deficiency is suspected or confirmed, though evidence for its efficacy in otherwise healthy individuals without deficiency is less robust. In summary, while magnesium is not a cure-all for heart rhythm disturbances, its use is supported by scientific evidence in specific clinical scenarios, especially when magnesium deficiency is present or with certain types of arrhythmias. Routine use for palpitations in the absence of deficiency or identified arrhythmia is not strongly supported by high-quality evidence.
