Hypomagnesemia-induced arrhythmogenic mechanisms.

Hypomagnesemia-Dependent Arrhythmogenic Mechanisms
inadequate effect of low Mg2+ concentrations against calcium in the AV node and ventricular myocardium
low magnesium causes malfunction of Na+/K+-ATPase, consequently creating a less negative resting membrane potential by decreasing the concentration of intracellular K+ and increasing intracellular Na+
hypomagnesemia-dependent hypokalaemia and hypocalcemia
direct effect of magnesium on preventing calcium overload in the myocite
PAF- related inflammatory cardiac response linked to arrhythmias
disturbance of the action-potential
