The top number is the systolic and represents the heart beating. The bottom is the diastolic, representing the heart at rest. When blood pressure gets too high, health problems can result. To help prevent serious illness, be aware of the complications that can occur when the bottom number is 100 or higher.

The two numbers that measure your blood pressure are written like a fraction: one number on top and one on the bottom -- for example, 128/82. The number on top is called the systolic pressure.. Systolic blood pressure measures the pressure inside your blood vessels at the moment your heart beats.

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.

Your blood pressure numbers and what they mean. Your blood pressure is recorded as two numbers: Systolic blood pressure (the upper number) — indicates how much pressure your blood is exerting against your artery walls when the heart beats. Diastolic blood pressure (the lower number) — indicates how much pressure your blood is exerting against your artery walls while the heart is resting between beats.

This causes a rise in the pressure within the arteries that we call the systolic blood pressure. When the heart relaxes, the blood pressure falls, but doesn't go to zero. This lull in the blood pressure is called the diastolic blood pressure. This is the bottom number. In general, we don't like the bottom number to be much above 85. If this number is too high, then the top number is usually high too. If only the bottom number is high, you may need a very low dose of a blood pressure medication. We call this isolated diastolic hypertension. It isn't that common, and usually does not cause any symptoms in people your age.

Answers from Sheldon G. Sheps, M.D. Yes. If you have a diastolic number — the bottom number of a blood pressure measurement — less than 90 millimeters of mercury (mm Hg) and a systolic number — the top number of a blood pressure measurement — greater than 140 mm Hg, you have a common type of high blood pressure called isolated systolic hypertension.

It is the most common form of high blood pressure in people older than age 60, but it is possible for younger people to be affected by this type of high blood pressure as well. Doctors now know that high systolic pressure is as important as high diastolic pressure — and even more important in people older than age 50.
