I did some internet research and started taking a B-complex vitamin and the palpitations stopped the very same day! This was exciting enough that I continued my research to try to solve other chronic issues I have such as acne, difficulty losing weight, and ongoing neuropathy (from my damaged spinal nerves) with a lot of success! I plan to post my success stories in other sections on earth clinic soon.
Among the more interesting things I learned while doing research was how long-term use of prescription drugs can deplete your body of certain vitamins. This is not something my doctors ever told me. With the smoking (I'm working on that) and a poor diet (I've since made some major changes), I think I was running on fumes, so to speak.
Since starting a good B-complex vitamin, I haven't had any heart palpitations at all.
Vitamins B1, B6 and B12

Also selenium and zinc deficiencies can cause heart palpitations. So if you can't take iodine because of the heart quivers you might have a deficiency you need to correct first.
