The top is high, if it is like that at all times or most of the time. If not, it could be a spike, but still should be checked. Where did U get this reading, at a drs. office, at home, or some machine in a store? My BP seems fine at home, yet when I go to the dr. it is up around 145/90, then after we talk for awhile and I calm down, it goes to about 125/78. They call that white coat syndrome.
U really need to get a home tester, and not a finger or wrist one, very inaccurate, and take your BP 3 times a day for a week or so to see how it really is. The store machines are usually off as well. When taken at home, it should also be about the same time each day.
Good luck....
