Hi, I suffer from anxiety and have had palps,ectopics, chest pain etc for years had ecg's, chest x ray, blood tests all ok apart from fast heartbeat. The thing is I have had constant palps and I'm due to have a major operation . I'm so scared that my heart will fail and I won't wake up. My consultant I'd not seem concerned but I'm petrified. I know I'm getting so anxious and its not helping the palps. My legs feel like jelly, and I can't et I feel all light headed. I the these palpatations they are horrible. Please help I need reassurance .
