What we usually call high pressure and low pressure, formally known as systolic and diastolic blood pressure, corresponds to the systolic and diastolic phases of the heart. When the heart contracts and ejects, the large arteries expand to hold blood, and the highest pressure that blood exerts on the walls of the arteries is the systolic blood pressure. When the heart relaxes, the aortic valve closes, and the arterial system retracts under its own elasticity, squeezing the blood to continue to move forward, and the lowest pressure value exerted to the blood by the arterial wall is diastolic blood pressure.
GIF low blood pressure is often common in young and middle-aged people, because young and middle-aged hypertension is characterized by diastolic hypertension, and the onset of diastolic hypertension is characterized by insidious onset, clinical symptoms after the onset of the disease are mild or no clinical symptoms, blood pressure changes have no obvious regularity, simple diastolic hypertension is the initial stage of hypertension, patients often have headache, dizziness, chest tightness, palpitations, discomfort, fatigue and drowsiness and other symptoms, with the increase of age, the course of the disease is prolonged, simple diastolic hypertension can be transformed into classical hypertension, It even progresses to simple systolic hypertension. Eventually, it will cause damage to important organs such as the heart, brain, and kidneys, such as heart failure, arrhythmia, atherosclerosis, cerebrovascular accident, kidney damage, and retinal dysfunction, while coronary heart disease, myocardial infarction, and stroke are the most serious complications of hypertension. Therefore, high blood pressure should not be taken lightly.
Aging, disease, smoking, obesity and other causes can change the structure and function of the arterial blood vessel wall, causing thickening, calcification and reduced elasticity of the arterial blood vessel wall. When the heart contracts, a large amount of blood rushes into the artery, and the artery cannot expand and expand to accommodate the blood, and the peripheral resistance increases, which will lead to the thickening of the left ventricle, heart failure and other cardiac impairment diseases, and in severe cases, it will even lead to arterial rupture and bleeding.

The high pressure is normal, but the low pressure is high?

Blood pressure is high and low blood pressure is the result of an increase in pulse pressure difference. It is more common in the following situations:
1. Simple systolic hypertension in the elderly:
It is a type of hypertension that is more common in the elderly, because with age, the elasticity of the large arteries decreases and the compliance of blood vessels decreases, which can cause an increase in systolic blood pressure, a low diastolic blood pressure, and an increase in pulse pressure difference.
2. Anemia, hyperthyroidism and other hyperdynamic circulatory states:
In patients with anemia and hyperthyroidism, systolic blood pressure increases due to accelerated circulation and increased cardiac output; Diastolic blood pressure decreases due to decreased vascular resistance, resulting in a relative increase in pulse pressure.
3. Receptor hyperresponsiveness, also known as primary hyperdynamic circulation, is mainly seen in young people, most of them are asymptomatic, some have palpitations, shortness of breath and other manifestations, the pulse and heart pulse are obvious, and the pulse pressure difference is widened. In fact, it is a functional disease of cardiovascular dysfunction caused by sympathetic hyperfunction.
Therefore, when blood pressure is high and low blood pressure is high, the above reasons should be considered, and corresponding tests can be done to confirm the diagnosis.

High pressure 130 This value is not high, it is a normal high value, within the normal range, 140 is the critical value of high blood pressure, your low blood pressure is 50, this value is below 60 It is a bit low, it may be caused by your recent poor sleep This will be an error in the measured value It is recommended to sleep well Test a few more times and measure a few more days in a row Take a look...

Hello! High pressure is systolic blood pressure of the heart, low pressure is diastolic blood pressure, high blood pressure, low blood pressure is low, it may be a symptom of some cardiovascular diseases, blood vessel narrowing When the heart contracts, the side pressure of blood on the blood vessel wall will be greater than normal, both high pressure and high pressure! Similarly, the amount of blood returned to the heart by the narrowing of the blood vessels is reduced, showing low pressure!
-
The low pressure is not very low, but the pulse pressure difference is a bit large, 125 65 60, and the normal is 30 40.
If the pulse pressure difference is too large, it is necessary to consider going for a color ultrasound examination of the heart, and if there is no structural heart disease, it is generally not related.
It is recommended to develop the habit of exercising, eating a balanced diet, cultivating a cheerful personality, and getting enough sleep. Live a regular life.

Because of the high and low pressure caused by the difference between sea and land, the air pressure is low in places with high temperatures, and high air pressure in places with low temperatures. The difference between sea and land heat causes the difference in sea and land pressure, which also causes the movement between the atmosphere, the most important is the three-circle circulation, the reason for which is the high and low pressure, and most of the world's climate formation depends on the atmospheric circulation, so it has a very important impact on the climate, taking Asia as an example: the continent is cold in winter, and the Asian high pressure is formed on the Asian continent, and the north wind or northeast wind prevails at this time, which is dry and cold, resulting in most parts of China being dry and cold in winter. In summer, the temperature of the Pacific Ocean is lower on land, and the high pressure is on the Pacific Ocean, at this time, the southeast wind prevails in China, and the air mass brings a large amount of water vapor from the ocean, resulting in the climatic characteristics of rain and heat in the monsoon region of China.
Low blood pressure and high blood pressure are high blood pressure. Hypertension is divided into primary hypertension and secondary hypertension. Most people with hypertension are primary. >>>More
First of all, I will tell you that your blood pressure is normal, and you have said that you are a little nervous when you take the test, and your heartbeat is faster than usual, which must have a certain impact on the measurement results, so you don't worry too much, it's okay. If you are overweight, drink less whole milk powder and drink low-fat ones. >>>More
If the patient currently has low blood pressure, high blood pressure, and low blood pressure, that is, the patient's current diastolic blood pressure is high and systolic blood pressure is low. This can lead to a decrease in pulse pressure for a number of reasons, such as if the patient currently has a large pericardial effusion or severe mitral stenosis, constrictive pericarditis, aortic stenosis, and severe heart failure. In addition, some people with hyperlipidemia, obesity, diabetes, or excessive blood viscosity may also experience this decrease in pulse pressure difference. >>>More
Many people will find that their high blood pressure is not high, but there is a significant increase in low blood pressure, and they will also feel more worried at this time, which is mainly due to unhealthy diet. >>>More
It is isolated diastolic hypertension.
Diastolic blood pressure can be increased due to a variety of causes, including increased peripheral resistance, increased stroke volume, and increased heart rate. The cause of your high blood pressure should be confirmed by examination from the aspects of high power source, poor blood vessels, and poor blood flow. It is more common in men and younger people, especially those with unhealthy lifestyle habits (smoking, alcoholism, lack of sleep), stress at work, lack of exercise, and lack of health care. >>>More
