Hi, I started having heart palpitations on Friday afternoon, I've always had them out of the blue before but it's just passed. These ones just seemed to carry on, and I've been having them every day since, sometimes they come and last half an hour and then go. It feels like my heart is weak and struggling to beat, sometimes I can feel it beat in my chest like 5 or 6 times in a row. It feels horrible and I can't stop worrying. I've been to the doctors and had an Ecg and he said there is nothing wrong, it's probably an ectopic beat. I just wondered why it's come On so suddenly. I don't drink, smoke take drugs or too much caffeine. Is it the anxiety catching up with me? Please help I can't go on like this.
