I don't think you should be worried as long as that is normal for you. Doctors now have changed the 120/80 rule and consider just under 120/80 to be normal. It varies from person to person and from day to day. I had mine checked and it was 110/60. A few days earlier it was 115/70. Your heart rate
is slightly elevated but you may have been nervous, have just walked around or any number of things can bring your resting heart rate up to 87.
