The attention on magnesium as a potential antiarrhythmic agent is founded on a small number of physiological assessments in human and animal models. 3, 4 Identifying practical and effective methods for managing AF is a clinical imperative. 2 AF is not only prevalent in the general population (≈3%, with much higher rates in older patients) but also a frequent comorbidity and risk factor in patients with a range of cardiovascular conditions, including heart failure and after cardiac surgery. This issue is clinically important in view of the high burden that AF poses, the increasing incidence of AF, and the association of AF with adverse long-term clinical outcomes. 1 However, like many interventions before it, supplementing magnesium levels does not necessarily lead to a successful cardioversion or better prevention of AF in high-risk groups. Low magnesium levels have been implicated as a risk factor for the development of atrial fibrillation (AF).
