My AF eposodes seem to have increased lately. I have been reading posts on magnesium and done a little research. I was out of rhythm this morning and decided to walk into town 2.7 miles. I impulsively bought some magnesium chelated tablets and took one aftet bussing home. Within an hour or so I was in sinus rhythm. Coincidence or what. The exercise or magnesium? I'm still in SR.

I HAVE read about some people who find eercise puts them back in SR but I don't think it's very common.

All I can say is I started magnesium supplementation about 10 weeks ago and I have gone from AF attacks once a week and a hospitalisation at least every 2 months to having had 2 minor occurrences that lasted no more than 10 minutes.

I started on plain old magnesium then went to chelated and am now planning to move over to taurate or citrate as my research indicates these two are the best of the bunch. I am also using magnesium oil spray intermittently. Coincidentally the 2 small AF episodes I had were on the same days I used the spray. Could be just a weird coincidence but am going to try again this week and see what happens.

But with saying all this you obviously should consult your Dr before you start getting deep into supplementation.

I should say that magnesium IV drips are pretty standard A&E response to AF here in Australia and have always worked for me.


Hi I live in Australia and have never heard of magnesium drips Who gives these and is it when you were hospitalised? Did they help?


Jill I have probably been hospitalised at least a dozen times (maybe more) with AF both on the Gold Coast and here in Sydney. I'd say at least half those has included a magnesium IV as part of the treatment to get me back into sinus rhythm. Did they help? I really think they did but who can know for absolute certainty? Recently the most I have been given a metoprolol and the IV drip so I have to think they have an effect. How often have you had to be hospitalised with your AF? I am surprised you have not been given a magnesium IV if you have been in more than a few times.


I have only had AFib for three months but it is persistent according to tests. Had a Cardioversion two weeks ago which has just failed. Am alson Metoprolol. I live in Wollongong area and see a cardiologist there. I will enquire about the magnesium drip Thanks.


Jill I have only ever seen a magnesium drip used in emergency situations. Our AFibs are also very different. Mine was cardioverted successfully (twice) and I probably used to go into AFib once every months and serious Afib once every 2 months. Mine tend to be where I go from 0 to 100 (or to be precise around 220 - 260 bpm) as opposed to consistent AF.

You should also consider magnesium supplements and discuss with your Dr. Magnesium is the most vital nutrient in our body for stabilizing heart rhythm.


Thanks so much Dave for the information you gave. I am researching magnesium as a supplement. Do not want to try an ablation yet as these don't seem to work a lot of the time and it seems a very invasive approach to me.

At this stage I am looking at lots of lifestyle improvement approaches, seeing a dietician, and exercise physiologist with cardiac experience and looking into supplements as well as seeing cardiologist. Although mine seems to be consistent, I do have times when it really races, often brought on by stress.

It if great to have this forum and hear others points of view.


Yes thanks dave a timely reminder. Its easy to get carried away.


Can I ask if you are on any other prescribed medication.

Thank you


Amiodarone 100mg, Metoprolol 50mg, Plavix 75mg and Aspirin 100mg


Excercise and physical work keep me in rhythm usually. All of my bad episodes and when I'm taking it easy and/or lying down. I believe that would apply to a lot of people with vagal type arrhythmia which I assume is what I have.

Only way you can tell with the mag is keep taking it and see what happens generally.

When we're treating farm animals for mag deficiency (and that's quite common), the effect is almost immediate if done intravenously but takes a few hours if done by another route.



I was put on a magnesium drip on my last visit to A+E and it didn't agree with me at all. I felt as though I was dying and hardly had the energy to speak and felt I was slipping into unconsciousness. Thankfully, a doctor trying to converse with me realised what was happening and took me off it and the effects soon wore off. It didn't stop my AF either and I was admitted to a ward where I stayed for several days.

Also the less active I am, the more chance I have of having an episode of AF.



It's bizarre isn't it? Such similar problems and so different in what works for us:) I am the opposite with exercise. If I exercise really hard (and I do mean REALLY hard) during the day an AF attack is likely that night or the next morning...

Hi Barry can I ask you what make did you buy


Holland and Barrett 150mg easy absorbtion. the ingredients state: magnesium bio bisglycinate "chelate"


Thank you Barry


Sorry to butt in but I started on chelate and after research and feedback from others here have found citrate or taurate would be wiser choices as far as effective absorption goes.

I am still getting through my chelated magnesium - I bought a bucketload once I found that after 3/4 weeks on magnesium my symptoms were greatly reduced.

Thats actually an understatement - I have not had an attack in about 10 weeks which for me is almost miraculous!

Again, sorry to butt in but thought it better to have you benefit from the lengthy reserved I did rather than start on chelated and realise there was something even better out there.

Magnesium oil is actually the best absorbed of all and if you don't mind the inconvenience of spraying it on and having to wait 20 mins it's definitely worth looking at. The magnesium is absorbed straight through your skin and into your bloodstream as opposed to having to make its way through your digestive system before finally being absorbed.

Many foods - spinach, nuts and others - have good amounts of magnesium. Spinach is supposed to have around 80 grams per half cup - however our soils are become so leached from commercial production often magnesium levels are nowhere near this. I live in Australia and found out last week from a nutritionist that we have some of the least nutrient rich soil in the developed world!


Thanks for the info
