Use our blood pressure chart to learn what your blood pressure numbers mean. Systolic, diastolic? The American Heart Association helps you understand the various levels of blood pressure and how high blood pressure or hypertension is defined. Also learn about prehypertension, hypertension, ...

Your blood pressure changes throughout the day based on your activities. A healthy systolic blood pressure is less than 120 mm Hg. A healthy diastolic pressure is less than 80 mm Hg.

Blood pressure is measured in millimeters of mercury (mm Hg). A blood pressure reading has two numbers. Top number, called systolic pressure. The top number measures the pressure in the arteries when the heart beats. Bottom number, called diastolic pressure.

February 13, 2025 - Isolated diastolic hypertension (IDH) takes place when the bottom blood pressure number (diastolic pressure) is high, while the top number (systolic pressure) remains within a normal range.

And even when we adjusted for pulse pressure, the conclusion about the low diastolic pressure still rang true. We actually looked at three different groups of pulse pressure — normal, wide and really wide. And it was true throughout. Low diastolic blood pressure increased one’s risk for ...

January 18, 2024 - Blood pressure levels can vary between individuals, but the American Heart Association (AHA) recommends a target blood pressure below 120 mm Hg systolic and 80 mm Hg diastolic.

April 1, 2022 - A systolic number of 120 to 129, with the diastolic measurement less than 80, is deemed "elevated." When it comes to diagnosing high blood pressure (hypertension), either number can be an indicator if persistently elevated.

To avoid potential harm, the 2018 European Society of Cardiology (ESC) Hypertension Guidelines have recommended an optimal DBP target of between 70 and 80 mm Hg for patients with all risk levels.18 Given the great influence of the 2017 AHA guideline and the argument that the diastolic J-shape ...

The BP reference data include the ... pressure range found in children. Normal BP is defined as systolic and diastolic blood pressures that are below the 90th percentile....

If your top number (systolic pressure) is consistently higher than 140mmHg, but the bottom number is healthy - this is known as Isolated Systolic Hypertension. If the bottom number (diastolic pressure) is consistently higher than 90mmHg but the top number is healthy - this is known as Isolated ...

February 2, 2021 - Normal — Blood pressure readings of less than 120/80 mm Hg are considered in the normal range. Elevated — Readings consistently ranging from 120–129 systolic and less than 80 mm Hg diastolic are considered elevated.

October 2, 2024 - This number is lower because the ... walls become more rigid and stiff. The normal range for diastolic blood pressure is 60 to 80....

For example, if your blood pressure is "140 over 90" or 140/90mmHg, it means you have a systolic pressure of 140mmHg and a diastolic pressure of 90mmHg.

January 12, 2026 - So, is 140 over 70 a good blood pressure? No, because the 140 figure indicates high blood pressure. How about 119 over 90? Again, no. The 119 figure is in the normal range, but 90 is higher than recommended.

December 19, 2025 - Blood pressure is recorded as two numbers, one over the other, such as 120/80. Both are measured in units called millimetres of mercury (or mm Hg). Systolic pressure: The top number, called the systolic pressure, is the pressure each time your heart contracts (or squeezes). Diastolic pressure: ...

October 11, 2017 - An ideal blood pressure for most adults is lower than 120/80 mm Hg (millimeters of mercury). This means your systolic (top) number is below 120 and your diastolic (bottom) number is below 80.

September 25, 2025 - Hypertension is diagnosed if, when it is measured on two different days, the systolic blood pressure readings on both days is ≥140 mmHg and/or the diastolic blood pressure readings on both days is ≥90 mmHg.

The first, or top number, is the ... Systolic pressure is the higher of the two numbers. The second, or bottom number, measures the force of blood in your arteries while your heart is relaxed between beats. The bottom number is the lower of the two and is called the diastolic ...

December 15, 2025 - Providers measure blood pressure using these numbers because it is a standard way of describing the force of the pulsing blood. Changes in the difference between the two numbers can signal a heart condition or other health problem. Your systolic and diastolic blood pressures are both important.

2 weeks ago - In adults in most societies, systolic blood pressure tends to rise from early adulthood onward, up to at least age 70; diastolic pressure tends to begin to rise at the same time but start to fall earlier in mid-life, approximately age 55.
