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.
Report Abuse. 1  The bottom number of a blood is called the diastolic pressure. while the top number is called the systolic pressure. The systolic pressure is always the top number and the diastolic pressure is always the bottom number. 2  The bottom number (diastolic) is the pressure in your arteries when the heart is relaxed. That is why there is more concern when the diastolic is a high number than when the systolic (top number) is high. If your bottom number is high, your heart is never getting the relaxation pressures it needs.
