Know Your Blood Pressure Numbers What Does the Diastolic Blood Pressure Number Mean? The diastolic reading, or the bottom number, is the pressure in the arteries when the heart rests between beats. This is the time when the heart fills with blood and gets oxygen. A normal diastolic blood pressure is lower than 80. But even if your diastolic number is lower than 80, you can have elevated blood pressure if the systolic reading is 120-129. 80-89 is stage 1 hypertension. 90 or more is stage 2 hypertension. 120 or more is a hypertensive crisis.

Diastolic Blood Pressure The number on top is the systolic pressure. It measures the pressure inside your blood vessels at the moment your heart beats. The number on the bottom is your diastolic blood pressure. It measures the pressure when your heart is between beats. Diastolic blood pressure changes frequently throughout the day. Things that can make diastolic blood pressure change within a few minutes include: 1  Posture. 2  Level of exercise.

- The diastolic blood pressure number or the bottom number indicates the pressure in the arteries when the heart rests between beats. A normal diastolic blood pressure number is 80 or less. A diastolic blood pressure between 80 and 89 is normal but higher than ideal.A diastolic blood pressure number of 90 or higher, on repeated measurements, is considered to be hypertension or high blood pressure.he systolic blood pressure number is always said first, and then the diastolic blood pressure number is given. For example, your blood pressure may be read as “120 over 80” or written 120/80.

High Systolic Blood Pressure High Systolic Blood Pressure. Systolic blood pressure (the top number in a blood pressure reading) refers to the pressure within the blood vessels while the heart is beating. If your systolic blood pressure is more than 140 mmHg, you have high systolic blood pressure. For most people, the specific cause for this is unknown, but risk factors include having diabetes, smoking, and being overweight.

What is low systolic and high diastolic blood pressure mean? The higher number in your blood pressure reading is your systolic blood pressure. That number represents the amount of pressure in your arteries when your heart is beating. The lower number is your diastolic blood pressure. That's the amount of pressure in your arteries when your heart is at rest, meaning between heartbeats.

Blood Pressure Numbers 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. Systolic blood pressure measures the pressure inside your blood vessels at the moment your heart beats. The number on the bottom is your diastolic pressure. Diastolic blood pressure measures the pressure in your blood vessels between heartbeats, when your heart is resting. Because your blood pressure changes so often throughout the day, it is best to use more than one reading to figure out your average blood pressure.

Know Your Blood Pressure Numbers A normal systolic pressure is below 120. A reading of 140 or more is high blood pressure (also called hypertension). The diastolic reading, or the bottom number, is the pressure in the arteries when the heart rests between beats. This is the time when the heart fills with blood and gets oxygen. A normal diastolic blood pressure is lower than 80. 90 or higher is high blood pressure. Our charts below have more details.

Isolated systolic hypertension: A health concern? 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.

Systolic and Diastolic Blood Pressure Systolic and Diastolic Blood Pressure. Systolic blood pressure (the top number) measures the amount of pressure that blood exerts on vessels while the heart is beating. Diastolic blood pressure (the bottom number) measures the pressure in your vessels between heartbeats. If systolic and diastolic blood pressures are too high, you have hypertension.

What does the bottom number of blood pressure mean? Best Answer: The bottom number (diastolic) is the pressure when your heart is resting (between beats). It's a measure of how flexible / hardened your arteries are. 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.

What Do Your Blood Pressure Numbers Really Mean? First, a breakdown of what your reading entails. The top number is your systolic pressure, or the pressure that arises from your heart pumping blood into your bloodstream, says Kevin Campbell, M.D., an assistant professor of cardiology at the University of North Carolina. The bottom number is your diastolic pressure. That’s the relaxation phase of the pumping process, when your heart’s ventricle is filling and getting ready to take in the next pump. Both numbers are important to your heart health. A normal blood pressure reading will clock in below 120/80. To put it another way, your systolic will be below 120 and your diastolic will be below 80. (Low blood pressure, called hypotension, occurs when your reading measures lower than 90/60.

Heart Failure  In-Depth Report Doctors call them systolic (the top number) and diastolic (the bottom number) blood pressure. Knowing them both is important and could save your life. When your heart beats, it contracts and pushes blood through the arteries to the rest of your body. This force creates pressure on the arteries. This is called systolic blood pressure. A normal systolic blood pressure is 120 or below. A systolic blood pressure of 120-139 means you have normal blood pressure that is higher than ideal, or borderline high blood pressure.

Blood Pressure: Highs, Lows & What's Normal The bottom number, called the diastolic pressure, is the measurement as the heart relaxes between beats. Normal blood pressure is a systolic pressure of less than 120 millimeters of mercury (mm Hg) and a diastolic pressure of less than 80 mm Hg, or 120/80 mm Hg, according to the American Heart Association (AHA).Having a blood pressure greater than 140/90 mm Hg is considered high blood pressure or hypertension.A blood pressure level between normal and hypertension, is called prehypertension, meaning it is higher than normal, but not high enough to be considered hypertension.s people age, they get plaque buildup inside the blood vessels, and the flexible walls of the arteries become stiff. Now, when the heart squeezes and pushes the blood out, the blood vessels can't expand like they used to do and sustain higher pressure.

What do the blood pressure numbers mean? Blood pressure is the force of blood moving through your arteries, and is measured with twonumbers. The first, or top number, is your pressure when your heart beats, called the systolic pressure. The second, or bottom number, measures the force of blood in your arteries while your heart is relaxed (filling with blood between beats). This is called the diastolic pressure. Blood pressure usually varies throughout the day. For adults, a blood pressure reading of lower than 120/80 is considered normal.

What causes a high systolic but a low diastolic reading? When a person is evaluated for high blood pressure), 2 values are recorded: systolic and diastolic blood pressures. Systolic (the higher number) is the pressure in the arteries when the heart contracts; diastolic (the lower number) is the pressure when the heart rests between contractions. A blood pressure reading is recorded as systolic /diastolic pressure, or systolic over diastolic..

- The diastolic blood pressure number or the bottom number indicates the pressure in the arteries when the heart rests between beats. A normal diastolic blood pressure number is less than 80.hen your heart beats, it contracts and pushes blood through the arteries to the rest of the body. This force creates pressure on the arteries. This is called systolic blood pressure.

Human Physiology/Print Version Diastolic pressure is the minimum pressure in the arteries and occurs when the lower part of the heart relaxes. Normal blood pressure is less than 120 (systolic) over 80 (diastolic), typically written as 120/80 mm Hg (read 120 over 80 millimeters of mercury).ow Blood Pressure Is Measured. Blood pressure is expressed as 2 numbers. These numbers represent the pressure against the walls of your blood vessels as the blood moves through them. Systolic pressure is when pressure is highest in the arteries and occurs when the lower part of the heart contracts.

What Does My Blood Pressure Reading Mean? Systolic blood pressure readings between 130 and 139 or diastolic blood pressure readings between 80 and 89 usually indicate STAGE 1 HYPERTENSION, which means the force of the blood pressure in your arteries is higher than normal, putting you at increased risk of life-threatening problems such as heart attacks and stroke.
