The heart palpitations are probably because the parasites are causing vitamin deficiencies. I had heart palpitations too, and my doctor recommended taking a strong multi-vitamin with a potassium supplement. Potassium comes in 99mg capsules. Start out with 3 in the morning and 3 at night. Take the multi every morning. The palpitations should stop within a week or two at the most, then just take the multi after that. It worked for me and has worked for many of my friends.
