My heart palpitates almost daily. I notice it especially whenever I get angry, upset, worried, nervous, I eat wheat, I eat too much, or I get tired. I m going to the doctor on Monday, but I m wondering if anyone has any ideas what s wrong? :/ Oh, I forgot to add... I m a 17-year-old male. I eat pretty healthily. I exercise regularly. I am not overweight (I am 6% body fat).
