For a normal reading, your blood pressure needs to show a top number thatâs between 90 and 120, and a bottom number thatâs between 60 and 80. When both your systolic and diastolic numbers are in these ranges, youâre considered by the American Heart Association (AHA) to be within the normal range for blood pressure.
In the past, it was commonly thought that the diastolic pressure or bottom number was the most important blood pressure number. This mistaken idea dates back to one of the early studies of the treatment of blood pressure, where only patients with diastolic blood pressure over 90 mm were allowed into the study.
