hi, i have been having palpitations. I just figured that it was menopause related since I am 56 years old and had not experienced any symtoms of menopause. However in the last three days it has increased, I am not having shortness of breath and otherwise feel fine. When to the pharmacy to take my blood pressure and after relaxing my bp was 138/77 which is normal for me. My pulse however was 109/110. I take Synthroid 150mcg for underactice tyroid for many years (no problems)
