For the past week I have been having heart palpitations. Its has been a month since I ve been to the hospital and had an EKG done and I was told that besides the beginning stages of high blood pressure my heart is fine. But I feel these palpitations more and more. So should I be worried? I m sure that since I don t have a primary care doctor at the moment there is so much the Emergency room can do. Should I be concerned ? I ve also been told that it could be due to stress on my nervous system .
