How many levels of hypertension are there?

1, SYS: systolic blood pressure

Systolic blood pressure is when a person's heart contracts, the pressure in the arteries rises, the middle of the heart contraction, the highest pressure in the arteries, when the blood pressure on the inner wall of the blood vessels is called systolic blood pressure, also known as high pressure.

2, DIA: diastolic pressure

is when a person's heart diastole, arterial vascular elastic retraction, the resulting pressure is called diastolic pressure, also known as low pressure.

3, PUL: pulse

for the human body surface can be touched by the arterial pulse. The human circulatory system consists of the heart, blood vessels, blood, responsible for the body's oxygen, carbon dioxide, nutrients and waste transportation. Blood flows into the aorta through the contraction of the heart's left ventricle and is squeezed, then passed to the arteries throughout the body.

Expanded Information

According to the World Health Organization, hypertension is diagnosed in adults with a systolic blood pressure of ≥140 mmHg or (and) a diastolic blood pressure of ≥90 mmHg. According to the World Health Organization, hypertension is diagnosed in adults with a systolic blood pressure ≥140 mmHg (21.3 kPa).

Systolic blood pressure ≤130mmHg (18.6kPa) is called normotension, and those in between are called critical hypertension; the so-called hypotension refers to the arterial blood pressure of systolic blood pressure is less than 12kPa (90mmHg). There are different differences between different age groups and different genders.
