What is diastolic blood pressure What is systolic blood pressure

Systolic blood pressure is the blood pressure during vasoconstriction, which is what we usually call high pressure; Diastolic blood pressure is vasodilatory blood pressure, which is low pressure. It is generally expressed as systolic and diastolic.

Large pressure differentials are common in older people and are mainly due to diastolic regurgitation due to degenerative changes in the aortic valve and insufficiency of the aortic valve. For people with high blood pressure such as these, it is advisable to start with a smaller dose of antihypertensive drugs to avoid further reduction of diastolic blood pressure (low pressure). Diastolic blood pressure is particularly low, especially in patients below 30 mm Hg, angina pectoris often occurs due to low diastolic coronary perfusion pressure and insufficient blood supply to the myocardium.

In severe cases, aortic valve replacement surgery should be considered.

Diastolic blood pressure is the pressure at which the heart relaxes.

Systolic blood pressure is the pressure at which the heart contracts.

Systolic blood pressure: within one cardiac cycle.

Ventricular systolic and arterial blood pressure rise to the maximum.

The value when blood pressure is measured first and when a sound is heard.

Diastolic blood pressure: within one cardiac cycle.

The maximum value reached by the drop in arterial blood pressure during ventricular diastol.

The value at the time of the last sound heard when blood pressure is measured.

Systolic blood pressure is the first sound heard, diastolic blood pressure is the value of the last sound when playing, and yours should be 160

90, high blood pressure stage 1.

Diastolic blood pressure: the pressure in the blood vessels when the left ventricle dilates; Otherwise, systolic blood pressure.

Contraction is high pressure.

Diastolic is low pressure.

It is the low pressure and high pressure of blood pressure measurement.

Ventricular contraction, blood flows from the ventricles into the arteries, and the pressure of blood on the arteries is the highest, called systolic blood pressure (commonly known as hypertension). Healthy artery walls are elastic, ventricles are dilated, arterial blood vessels elastically retract, blood continues to flow forward slowly, but blood pressure drops, and the pressure at this time is called diastolic blood pressure (commonly known as low pressure).

When the doctor records blood pressure, if it is 120 80 mmHg, 120 mmHg is systolic and 80 mmHg is diastolic.

Normal people will have a certain amount of blood pressure increase during exercise and emotional agitation. Generally speaking, systolic blood pressure is mainly related to cardiac output, which increases during exercise and increases systolic blood pressure. Diastolic blood pressure is mainly related to resistance to blood flow, particularly arteriolar caliber.

If the arterioles constrict, the caliber shrinks, and the resistance to blood flow increases, and diastolic blood pressure increases.

1. sys: systolic blood pressure.

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

2. DIA: diastolic blood pressure.

When the human heart is dilated, the pressure generated by the elastic retraction of the arterial blood vessels is called diastolic blood pressure, also known as low pressure.

3. PUL: pulse.

It is a palpable arterial pulse on the surface of the human body. The circulatory system of the human body is composed of the heart, blood vessels, and blood, which is responsible for the transportation of oxygen, carbon dioxide, nutrients, and waste products. Blood is squeezed into the aorta by contraction of the left ventricle of the heart and then travels to the arteries throughout the body.

1. Systolic blood pressure is the lateral pressure on the blood vessel wall generated by the blood injected from the ventricles when the heart contracts, commonly known as high pressure. At the end of diastole, the blood temporarily stops shooting into the artery, and the blood that has flowed into the artery continues to flow by the elasticity and tension of the blood vessel wall, and there is still pressure on the blood vessel wall, and the blood pressure at this time is called diastolic blood pressure, commonly known as low pressure.

2. The normal range of systolic blood pressure in adults is 90 140 mm Hg, and diastolic blood pressure is 60 90 mm Hg.

Answer] :d blood pressure in children increases with age, and Heng Xian Ke Yan Hu uses the following formula to calculate: systolic blood pressure = age 2 +80mmHg, and 2 3 of this value is diastolic blood pressure. Tell the auspicious slag.

The most important thing is the systolic blood pressure, this value can not be higher than 150, refers to the highest pressure, once it exceeds this standard, the heart is likely to bleed in the process of contraction, there may be a high pressure, overwork, will affect blood circulation.

Systolic blood pressure is more important, and when the elderly over 50 years old are at risk of high blood pressure and cardiovascular disease, if the systolic blood pressure increases, it is more likely to cause cardiovascular and cerebrovascular diseases.

Systolic blood pressure is more important, because if the systolic blood pressure is too high, it is easy to suffer from cardiovascular and cerebrovascular diseases, and if the systolic blood pressure is too low, it will cause arteriosclerosis and anemia and other diseases.

Systolic blood pressure can be said to be particularly important, and healthy people will be at 90 139. And it can protect blood vessels and the heart.

A quick explanation of systolic blood pressure and systolic blood pressure. We all know that their hearts are constantly vibrating, in the case of this fibrillation, the heart carries out the whole process of the body's blood circulation system and blood supply to the body, and the heart rate level we measure refers to the pressure value of the blood on the aortic blood vessel wall during the circulation process. A low value means that when the heart is closed, the blood in the heart flows back to the body, and the amount of blood in the blood vessels is more, and the pressure on the aortic blood vessel wall is greater, <>

Therefore, it is called systolic blood pressure; When the left ventricle of the heart is located, part of the blood in the capillaries flows back to the heart, and the capillaries still have to ensure a certain pressure to supply blood to each human organ in the body. The continuous convergence of the heart and the left ventricle promote the flow of blood pressure values forward, and the pressure on the blood vessel walls when the blood flows in the capillaries is called the blood pressure value. When the heart closes, the pressure of blood on the walls of the blood vessels is high, which is called systolic blood pressure.

In the left ventricle of the heart, the pressure of blood on the walls of the blood vessels is low, called systolic blood pressure. Systolic blood pressure rises further with age, while systolic blood pressure tends to decrease.

Therefore, there is a type of high blood pressure called "isolated systolic hypertension", which is more common in the elderly. At this time, the increase in systolic blood pressure is large, and the predictive value of cardiovascular and cerebrovascular diseases is higher than that of systolic blood pressure; We all know that there are two values when the body's blood pressure is measured, one is systolic blood pressure and the other is systolic blood pressure. Usually many people only understand the main manifestations of hypertension when systolic blood pressure increases, which is not good for the body, but many people ignore the increase in systolic blood pressure, in fact, increased systolic blood pressure is the main manifestation of hypertension, and even more risky.

Blood pressure is the energy source that promotes the movement of blood through the capillaries, which refers to the lateral pressure that acts on the blood vessel wall per unit area as the blood flows. When the left ventricle of the heart is in the later stage of the left ventricle of the heart, the blood temporarily stops shooting into the aorta, and the blood injected into the aorta flows again by the elasticity and tension of the blood vessel wall, and there is still pressure on the blood vessel wall, which is called systolic blood pressure, also known as low voltage. When the human heart is closed, the pressure in the aorta rises, and the pressure in the aorta is the highest in the middle and late stages of the heart's contraction, and the pressure of the blood on the capillary lumen is called systolic blood pressure, also known as high pressure.

Both are very important, after all, a person's physical health depends on these two indicators, and only when they are normal will your body and health be revealed.

Both of these are particularly important, both of which can reflect the health of one's body, and should be taken seriously.

It is very important that blood pressure is divided into diastolic and systolic blood pressure, which is the most important way to supply blood to the body. Therefore, we should strictly monitor our blood pressure.
