Question: What measurement of magnesium status is best to use for arrhythmias?I assume by "measure" you mean a measurement of nutritional status, in which case I think you want to look at the serum level. think that if you're trying to fix a problem with the serum level, you probably at some point want to look at the red blood cell level and the urine level. One of the ways that magnesium could impact the arrhythmias would be through influencing other minerals, and so I would not recommend just looking at magnesium on its own. You definitely have to look at the calcium levels, the sodium levels, the potassium levels, and those would be the big four. . This Q&A can also be found as part of a much longer episode, here.
