Can a magnesium supplement help resolve pvcs?

Yes: It all depends on what's causing the pvcs. But if your magnesium is on the low side, supplementing mg can help prevent pvcs from deteriorating into a more serious rhythm like v tach or v fib. Usually, mg is an add-on to another cardiac med but you should discuss your treatment options and purpose of each med with your cardiologist.

Can help: If magnesium level is low, if you take supplements, pvcs can resolve, but if mag level is normal, taking mag supplements may not help.
