a large pile of vitamin pills, calcium supplements

Q. I used to take verapamil for occasional supraventricular tachycardia. Four years ago I switched to magnesium, alternating 250 mg one day, 500 mg the next.

No more irregular heart rhythm. In addition, I sleep better and have no more constipation. Since I have no prescription insurance, I have saved myself a lot of money!

A. A study that provided women with less than half the RDA for magnesium (which is 320 mg/day) found that while on the reduced regimen they had significantly more supraventricular beats (American Journal of Clinical Nutrition, March 2002). Magnesium also is known to be effective against constipation.

    I was diagnosed with SVT (supraventricular tachycardia) a year ago and was prescribed Cardizem. I took the Cardizem whenever I felt tachycardic and didn’t take it every day. Then I noticed I was needing to take it every day. Sometimes I would still have tachycardia even when I had taken the Cardizem. My cardiologist was gently nudging me to have the ablation procedure.

    Upon a routine visit to my GP, I saw the nurse practitioner, who suggested taking Magnesium 250mg twice a day (chelated and with Malic acid to aid absorption). She said to try the magnesium before planning to have the ablation. She asked what my water source was, and I told her we have filtered water with reverse osmosis—so I’m not getting minerals in my drinking water. Also I’m 66 years old, and as we get older it may be more difficult to absorb magnesium in the gut. It’s been two weeks, and I haven’t had ANY tachycardia and I haven’t taken any Cardizem. I’m sleeping better and have had NO palpitations or irregular heart beats. It’s only been two weeks, but it feels pretty amazing.

      Hi Jeanie, Would you mind telling me the brand of Magnesium you use? It is chelated and with Malic acid, will that be on the bottle? I have afib and had the ablation in 2011. Felt awesome afterwards, ans still feel great. But have a flutter occasionally now. (taking 25 mg Metoprol 2 times a day). But would like to know more about the Brand etc. I’m also 65. Thank you for your time.

        I am confused as to what type magnesium to get for afib or palpitations. Magnesium oxide, chelated and with Malic acid? Information will be appreciated.

          Magnesium citrate is less likely than magnesium oxide to cause diarrhea.

          I have had a moderate to severe heart palpitations for several years. My mother had a severe case and took verapamil. She died of a heart attack at the age of 60. I read that magnesium was used for treating palpitations so I researched and found Smart Mag on Amazon. It has stopped my palpitations and if I forget to take a dose I will have an attack. You have to buy the right kind of magnesium not the regular magnesium oxide you get at the drugstore. The Smart Mag is a proprietary blend that affects the brain and the heart. I hope this information helps. Dawn

    I have had bad arrythmia’s for 3 three years. Gone into AFIB 3 times. Ablation was scheduled. Read about magnesium and bought a bottle of calcium/magnesium at Whole foods. Symptoms quit in 4 HOURS!!! 400mg per day. Cardiologist seemed disinterested. Best thing I’ve ever done. Helped my mental outlook as well. Feel like a kid again. I tell everyone I can about this. Proof is in the pudding!!!

      Hi Brian- can you tell me which type of magnesium you took? As I am reading about AFIB and magnesium supplements, there seem to be several. Any input would be appreciated.

      Thanks,
      Chase

    Your response was confusing and, not being knowledgeable on supraventicular tachycardia, I could not tell if magnesium was good or bad. I have AFib. The comments section was very helpful in clearing it up for me and giving me worthwhile advice.

    I have had a irregular heart beat most of my life. I am 48 years old. The doctors have diagnosed me with mitrovalve prolapse which I don’t have. Then atrial fib which I don’t have.
    I was diagnosed with breast cancer august 2011. During my chemo the skipping, fluttering, palpitation and quivering got a lot worse. My oncologist prescribe 400mg of magnesium oxide twice a day. My blood work showed my magnesium level was at 1. Should be between 2 to 3.5. I have been on magnesium for 6 weeks. No more palpitations or irregular heart beats. The magnesium oxide is really working for me. I advise anyone with a irregular heart beat to get your magnesium checked.

    Magnesium is central to the nutrient that the body requires for your muscle tissue, bone fragments, center, anxiety as well as defense mechanisms to work correctly. Magnesium is central to the nutritional that must definitely be supplied by this diet. Dieting lower in magnesium, particular medicines as well as health conditions may cause the insufficiency. If you’re prone to the insufficiency, magnesium supplements will help you obtain the correct amount associated with every day magnesium. Nevertheless, higher dosages associated with magnesium may place you in danger of severe unwanted effects, therefore speak to your physician before you take Magnesium supplements.

    I just found out that Magnesium is very important in treating high blood pressure. I have been very pleased taking one Phillips’ Milk of Magnesia tablet a day along with a potassium sparing diuretic.
    Not only has my blood pressure come down, I am no longer constipated and my skin cleared up. Amazing!

    I have sick sinus syndrome and had a pace maker implanted six years ago. I also take 400 mg of magnesium oxide per day. It makes all the difference. If I skip a day I can tell it.

    I had the same experience–started taking magnesium because I thought it would be good for bone health. Bouts of sudden arrhythmias stopped. So did muscle tension that I didn’t even know I had til it stopped. I take 250mg twice a day.

    I have a friend undergoing chemo/radiation for lung cancer. She’s experiencing a constipation problem. I’m glad to have this info to pass along to her.
