Heart palpitations

Andreas,

I've had heart palpitations ever since I came down with candida and dysbiosis in the intestines. Now, I'm trying to use liver and colon cleansing to get rid of the dysbiosis and improve my digestion. I tend not to fear something as much if I understand it, so I was wondering if you can explain why heart palpitations occur when digestion is poor and the flora balance is off in the intestines? I've always wondered and sometimes, although the palpitations aren't severe, I get a little scared. Also, relating to the heart, is it possible if you're still young to get rid of whatever plaque may have built up in the arteries if you change your diet? I'm also wondering if the palpitations may be caused by plaque?
