@tntfal First, PACs are benign.......................until their burden, as it is called, reaches about 3% of all beats in any 24 hour period. After that, morbidity rises in the populations polled during the research described by the article I read. This means you can have literally hundreds of PACs every day before your EP would say it's time to do something concrete like to perform a catheter ablation. (The typical heart beats around 38-40K times each day, and 3% of that is around 1200 beats.)

Metoprolol doesn't stop an arrhythmia. It's a 'rate control' medication used to help keep the rate down when your heart is in a tachyarrhythmia. So, it keeps a lid on the high rate....supposedly. Didn't work especially well for me, and as it does for a great many whose hearts are not otherwise defective, and are healthy, it can put us into bradycardia where fainting, swelling extremities, and poor organ function become potential problems.

The salt of magnesium most easily absorbed by the system is magnesium citrate. It is also the form that can give you 'the trots' if you overdo it. So, most physicians recommend magnesium glycinate or bis-glycinate as the next best thing. The other salts, taurate, malate, threonate, etc, have mild benefits for one or more specific conditions, but the evidence is not overwhelming.

It would not be unreasonable to start salting yourself with 200 mg PO, but it's hard to say if you don't know your current RBC levels of magnesium? Were you offered that test to establish a baseline? It would be a great idea. What if you're already skirting the highest point in normal range for RBC Mg? Would it be useful to begin adding 200 mg PO? I would think not. Or, if it's the other direction, would a mere 200 mg be sufficient to get you properly infused and rid of the PACs.....IF....the PACs are being caused by low Mg? Several questions that need addressing in my opinion.

@tntfal You said ,"...I don’t really want to be medicated..."

Supplements ARE medication, they just don't require a prescription, and unfortunately can have adverse effects on some people and can interact with other medications. Further, in the US supplements are not regulated and inspected, so you need to do your own due diligence to find pure, quality products that contain what the label says and nothing else. If you have a healthy diet, most likely you get enough from your food, and the supplements are not without unpleasant side effects like diarrhea and bowel urgency.

Please have your magnesium levels checked BEFORE supplementation. Your body stores magnesium in your bones to release if your body needs it, and taking too much is a waste of money because your body eliminates it.
