Blood pressure is measured using two numbers: The first number, called systolic blood pressure, measures the pressure in your arteries when your heart beats. The second number, called diastolic blood pressure, measures the pressure in your arteries when your heart rests between beats.

What is the difference between DIA and SYS?

Your systolic blood pressure is the top number on your reading. It measures the force of blood against your artery walls while your ventricles — the lower two chambers of your heart — squeeze, pushing blood out to the rest of your body. Your diastolic blood pressure is the bottom number on your reading.

What does high SYS and low Dia mean?

For example, a healthy reading is below 120 over less than 80. If your systolic blood pressure is higher than 130 but your diastolic blood pressure is under 80, that’s called isolated systolic hypertension. It’s the most common kind of high blood pressure in older people.

What is SYS on blood pressure machine?

What Does the Systolic Blood Pressure Number Mean? When your heart beats, it squeezes and pushes blood through your arteries to the rest of your body. This force creates pressure on those blood vessels, and that’s your systolic blood pressure.

What is the normal SYS DIA and pulse?

A normal blood pressure reading almost always falls within the 120 to 130 beats per minute range. If someone is in excellent physical condition, the heart rate will beat at 120 or less beats per minute, systolic pressure. The diastolic pressure in a normal blood pressure reading will be between 80 -90 beats per minute.

Is low diastolic bad?

Isolated diastolic hypotension can be especially dangerous because it can decrease blood flow to your heart. You may be at higher risk if you have coronary artery disease. Over time, isolated diastolic hypotension can cause heart failure. In fact, it may be one of the most common causes of heart failure.

What does SYS DIA mean?

Your systolic pressure (the top number) is the pressure of the blood in your arteries when your heart contracts or beats. Your diastolic pressure (the bottom number) is the pressure of the blood in your arteries between beats, when your heart relaxes.

How much DIA is normal?

Normal: Less than 120 millimeters of mercury (mm Hg) for systolic and 80 mm Hg for diastolic. Elevated: Between 120-129 for systolic, and less than 80 for diastolic.

What is a good SYS and DIA?

For a normal reading, your blood pressure needs to show: a systolic pressure that’s above 90 mm Hg and less than 120 mm Hg, and. a diastolic pressure that’s between 60 mm Hg and less than 80 mm Hg.

What does Sys and Dia mean in blood pressure?

In blood pressure readings, “dia” refers to diastolic pressure. Diastolic and systolic readings are expressed as two numbers, one atop the other and divided by a line. The diastolic is the bottom number, and represents the pressure in the blood vessels when the heart is at rest.

What is the difference between systole and diastole?

The key difference between systole and diastole is that systole refers to the contraction of atria and ventricles, forcing blood to enter into the aorta and pulmonary trunk, while diastole refers to the relaxation of atria and ventricles, allowing the filling of heart chambers with blood.

How to read the SYS Dia pulse?

Locate the systolic pressure reading on the blood pressure monitor.

What is the difference between systolic and diastolic pressure?

Blood pressure readings are given in two numbers. The top number is the maximum pressure your heart exerts while beating (systolic pressure), and the bottom number is the amount of pressure in your arteries between beats (diastolic pressure). The numeric difference between your systolic and diastolic blood pressure is called your pulse pressure.
