Vixmom, as someone who gets tachycardic from time to time, I definitely recommend that you see a cardiologist. Your condition is worse than mine, but I also will pass on what works for me: 100-200 mg magnesium plus 99 mg of potassium, taken with a glass of water. The doctors I'd seen failed to mention the importance of both minerals to heart health and I wasn't satisfied with the "If you don't like the symptoms, take the meds" attitude of one of the UCLA cardiologists. This formula has never failed me. It was, in fact, a cardiologist who told me about the potassium and a large glass of water. I was already taking magnesium for a rapid heart rate, which usually takes care of it for me on its own. Since I'd rather not get tachycardic in the first place, I now make sure I take both magnesium and potassium in small doses throughout the day. Magnesium also got rid of my migraines. I told an osteopath I know and now she takes it and got rid of her migraine.
I also recommend Stephen Sinatra's book, "The Sinatra Solution: Metabolic Cardiology."
Vibes you get it under control quickly.
Thank you Jeanne, where do you get the magnesium and potassium? I already take vitamins very day that are supposed to give me 100% of all requirements
Nutritional requirements vary greatly from person to person. The levels the government quotes are usually the very lowest needed to stay alive--not provide optimum health. Plus, stress depletes certain nutrients, especially magnesium and the B vitamins.
I like Source Naturals Ultra Mag because it contains five types of magnesium. Some forms are fast-acting, others slower. Each has its own pros and cons. 200 mg per tablet.
I also like Source Naturals Mag Citrate, 133 mg per tablet. A less expensive form.
Do not buy 400 mg tablets, as it too much at once (for the gut) for most people. It can give you loose stools.
I'm currently using NOW Potassium Citrate 99 mg/capsule.
There are many other brands available. I use Vitacost.com, as they have great prices, lots of sales and promos, and a huge selection.
Please, please, please see the cardiologist. As Jane mentioned, they'll probably ask you to wear a Holter monitor for 24-48 hours. This is necessary to pick up intermittent heart issues. Mine never showed up on an EKG, but did show up on the Holter. It's not uncomfortable to wear, but plan accordingly as you can't shower or bathe while wearing it. (One of the things the doctors didn't mention!) If your problem is intermittent like mine you may find that adjustments to your diet or supplements mean that you either don't need the powerful heart drugs or you can get along quite well on a lower dose. And if you have a deficiency of either magnesium or potassium you'll benefit in other ways by correcting it.
One more thing: most doctors use a CBC to check magnesium levels, but magnesium isn't stored in the blood, so it's not an accurate indicator. Try taking a bit more and see if you feel better. Brown rice is an excellent source of magnesium. Carolyn Dean's book The Miracle of Magnesium is a very easy read.
