Why the study?
Magnesium is crucial for the cardiovascular system and its deficiency causes arrhythmias, but the effect of oral supplementation on pediatric ventricular extrasystoles needed determination.
Does oral magnesium supplementation reduce the frequency of ventricular extrasystoles in children without structural heart disease?
Does oral magnesium supplementation reduce the frequency of ventricular extrasystoles in children without structural heart disease?
Oral magnesium supplementation may effectively suppress ventricular extrasystoles in children without structural heart disease, regardless of baseline serum magnesium levels.
May support magnesium supplementation for pediatric ventricular extrasystoles; hypothesis-generating and requires randomized confirmation.
Magnesium (Mg) is a crucial element for cardiovascular system and its deficiency results in a variety of cardiac arrhythmias. The aim of this study is to determine the effect of oral Mg supplementation on the frequency of ventricular extrasystoles (VES) in children. Magnesium supplementation was given to 42 children who had VES without structural heart disease. Clinical, electrocardiographic, and Holter monitoring studies were reviewed. The mean baseline 24 h VES burden on Holter monitoring was 10.26% ± 4.13% and it was decreased to 6.62% ± 3.88% after. There was no significant difference between the pre-treatment serum Mg levels and the decrease in the frequency of VES. In conclusion, oral Mg therapy was found to be effective at suppressing VES in children regardless of serum Mg levels. Large and randomized studies are needed to demonstrate the effect of magnesium on VES suppression.
