Why is there a big difference in blood pressure between the left and right hands?

There are such situations: 1 Look at which hand you have is the forehand, the side that mainly does the work, often the blood pressure value is high there, because the blood vessels are thick.

2 Some people have had surgery on one side, or have been injured and damaged blood vessels, so the amount is low.

3. There are people like hemiplegia on one side, due to blood clot obstruction and long-term inactivity, the blood pressure will be much lower than that of the good side. 4. When some people have congenital heart disease, such as coarctation of the aorta, patent ductus arteriosus, etc., resulting in hemodynamic changes, there will be low blood pressure in the left upper limb.

5. Then there is, when you measure, you first touch the strong beating place of the brachial artery, and then place the cuff to measure blood pressure, and put the stethoscope to listen to the place where the brachial artery beats strongly, which can reduce the error of auscultation.

This is determined by physiological factors, and normal blood pressure in the right arm should be about 10 mm Hg higher than in the left arm.

Blanch your feet with hot water for 30 minutes every day, heat the water in time when the water is cold, and sweat for the hot ones to comb your hair back with ten fingers before going to bed 5. 6 times to push the small belly from top to bottom 200 times, it is better to be comfortable. It's very good for you, please try it and wish you success.

Men on the left and women on the right, that's all that is known, and men breathe in the abdomen and women breathe in the chest. The heart is on the left side, and the right side is not where the heart is located, so the arterial blood output from the heart does not travel the same length from the ventricles to the left and right superior brachial arteries, so the blood pressure may be the same.

Whether you use an electronic blood pressure monitor or not, there will basically be a little error in this. Traditional blood pressure monitors rely on human hearing to listen, and generally there will be a slight difference according to each person's hearing, but the general difference is not very large. Most of them are based on the blood pressure of the left hand, because many people say that the heart is on the left side, but I don't know if it's right or not.

Blood pressure is in a dynamic position and does not have a particularly precise value.

The difference in blood pressure values between the normal left and right arms is 10-20 10mmHg is normal, but your difference is a little big, but I don't know if the measurement is accurate, if the difference is still so big after going to the hospital for examination, it is necessary to consider that there are blocked lesions in the subclavian artery and distal end on one side, such as Takayasu's arteritis, atheromatosis, etc., may mine be useful to you, I wish you health and safety.

No way, there is a gap between the left and right, but there can't be such a big difference, you'd better test it again.

In the case of blood pressure measurement, it is normal for the right hand to be different from the left hand. Generally, the largest value is dominant. There is often a difference between the standard value measured by the right hand and the left hand, because the aortic fluidity of the upper and lower clavicles is different, so the blood pressure value on the right side is about 10mmHg higher than that on the left side, which can be omitted and excluded in medicine.

Many people do not know which hand should be measured in the case of blood pressure, some people measure the right hand and the left hand together, but the measured data is wrong, this situation is normal, because the inflow of the cervical aorta is different, so it will lead to the existence of this kind of pressure difference, if you want to really measure accurately, then measure both hands to see, which hand has high blood pressure, and take that hand as the standard. When your blood pressure is high, you must pay more attention to these aspects:

Change your diet. High blood pressure must not be overeating, most of every food needs an effective combination, the most important thing is to eat less salt. If you often eat high-sugar, high-calorie and high-salt ingredients, your blood sugar will keep soaring.

People with high blood pressure have strict dietary rules. Therefore, when eating food, be sure to choose some foods that have the effect of lowering blood pressure, such as garlic, black beans and lettuce. At the same time, you can also eat some animal fat and animal offal.

Patients with high blood pressure should pay attention to exercising moderately. Exercise can reduce the occurrence of many diseases, and at the same time improve one's own immunity, which has the effect of lowering blood pressure for patients with high blood pressure. Mainly because exercise can promote a blood cycle, which has a carbohydrate reduction effect on people's body.

And exercise can improve our appetite, prevent some serious constipation, and their sleep quality is particularly good, so fitness exercises must be done, and to stick to the end for a long time, this kind of fitness exercises, including walking, running and swimming. Aerobic exercise is generally recommended.

Theoretically, the blood pressure of the left and right upper limbs should be the same, but the left and right upper limbs of each person are not completely symmetrical, so the blood pressure of the left and right upper limbs is not exactly the same. Generally, there will be one side that is high, the specific side is higher for each person, when measuring blood pressure, the higher side should prevail, and try to measure the higher side blood pressure every time monitoring, for example, the blood pressure of the left upper limb is often higher than that of the right upper limb, and the blood pressure of the left upper limb should be monitored as much as possible when monitoring blood pressure, and the blood pressure of the left upper limb shall prevail.

This is mainly related to the structure of the human body, and this will happen when the left upper limb and right upper limb of each person are not perfectly symmetrical. Generally speaking, it depends on the higher side.

It may be related to the position of the heart, the heart is biased to one side, and such a difference will naturally occur, generally speaking, the higher side shall prevail.

1. It is normal for the head of the limb to be weak, and the blood pressure difference between the left and right hands is 10 20mmHg.

2. Under normal circumstances, the blood pressure of the right hand will be 10 20mmHg higher than that of the left hand.

3. When measuring blood pressure, the brachial artery blood pressure is measured, the right brachial artery comes from the branch of the brachiocephalic trunk, and the left hand brachial artery comes from the left subclavian artery.

4. The brachiocephalic trunk and the left subclavian artery both come from the aorta, while the brachiocephalic trunk is a larger branch of the aorta, and the left subclavian artery branch is smaller, so the blood pressure on the right side is naturally higher.

5. When measuring blood pressure, it is usually mainly to measure the blood pressure of the right upper arm. Only first-time patients should have their left and right arms measured at the same time and recorded.

6. The normal blood pressure range is (90 140) (60 90) mmHg, and the pulse pressure difference is between 30 mmHg and 40mmHg.

There are two reasons why the blood pressure of the left and right hands of people is different.

Reason 1: The blood pressure of the left and right hands of people is different, because the blood pressure on the left and right sides of the human body is different due to the blood vessels on both sides and the position of the heart. Because the subclavian artery on the right side branches off from the aorta first, blood pressure on the right side is about 10 mmHg higher than that on the left.

It is said that the right brachial artery is the first branch from the aorta, while the left hand brachial artery belongs to the third branch of the aorta. When the blood in the aorta reaches the third branch, it consumes more energy than the first branch, and the blood pressure may be lower than in the right hand.

Reason 2: In addition, sometimes there will be unilateral artery occlusion, such as axillary artery occlusion, subclavian artery occlusion, resulting in the blood pressure on the affected side is significantly lower than that on the opposite side.

The selection of the time of the accurate method of measuring the blood pressure of the left and right hands.

The best time to measure blood pressure is in the morning before you get up for breakfast; If you're measuring at night, it's best to take it before you're ready to go to bed.

Diet for an accurate way to measure blood pressure in both left and right hands.

Do not smoke or drink coffee, strong tea or caffeinated beverages within 30 minutes before the measurement, and do not take medications that affect blood pressure.

An accurate way to measure blood pressure in the left and right hands to maintain emotional stability.

When measuring blood pressure, you should not be too nervous, you should keep yourself quiet for at least 10 minutes before the measurement, and you should be calm and relaxed as usual, so that the blood pressure measured is more accurate.

The procedure of the preparation method for measuring the blood pressure of the left and right hands.

Before the measurement, the mercury column of the sphygmomanometer should be at the vertical zero level, the right upper arm should be exposed, the cuff should be tied flat and comfortable on the right upper arm, and its tightness should be enough to fit into the tips of the two fingers, and the lower edge of the cuff should be placed about 2-5cm above the elbow fossa in front of the elbow joint, so that the inflated air bag is just located at the brachial pulse site.

An accurate way to measure blood pressure in the left and right hands: a good blood pressure monitor.

At present, there are generally three types of blood pressure measuring instruments on the market: 1. Mercury column blood pressure measuring instrument and the one commonly used by doctors in hospitals. 2. Electronic arm blood pressure meter, 3. Electronic wrist blood pressure meter.

If you want to check your blood pressure but don't have enough money, you can consider an electronic blood pressure monitor. Electronic blood pressure monitors also include wrist and arm blood pressure monitors, and arm blood pressure monitors are more accurate than wrist blood pressure monitors. If you have the ability at home and want to measure accurately, you can buy a desktop mercury column blood pressure monitor.

If the blood pressure of the left and right hands is different, the measurement value on the side with higher blood pressure should prevail. In general, because the right subclavian artery is separated from the aorta, the blood pressure on the right side is about 10 mmHg higher than that on the left. So this difference is negligible.

The difference in systolic blood pressure between the two sides of a normal person is within 10 mm Hg, which is normal, and the difference between the two hands is related to acquired factors, and the right hand is often moved and exercised.

Hypertension is a common disease in life, and many people suffer from hypertension, especially in middle-aged and elderly people. Patients with high blood pressure should measure their blood pressure regularly and take medications to lower their blood pressure so that they can be healthier. Patients with high blood pressure should master the correct way to measure blood pressure, so that they can get accurate blood pressure values.

The most common way to measure blood pressure is to use a sphygmomanometer, which uses a cuff compression method. When many people measure their blood pressure, they have a doubt about whether it is better to measure blood pressure with the left hand or the right hand. <>

In fact, if you want to get an accurate value, you can measure it with both hands, and it is more accurate to take the highest value. Blood pressure is measured with the left hand, and the aorta below the clavicle is measured. This artery is particularly small, and the diameter of the blood vessel is also small, so the blood pressure value will fluctuate less.

Measuring blood pressure with the right hand is the aorta of the head and arm, which has a large diameter, so the blood pressure fluctuation will be greater. Blood pressure measured with the right arm will be higher than with the left arm. <>

If the difference between the two measurements is 5 10mmHg, there is no need to worry, this is normal. If this value is exceeded, then there may be a problem with the blood vessels, and it is necessary to go to the hospital for a check-up in time. When measuring blood pressure, you can measure it once with your left hand and once with your right hand, and the highest value of the two is the most accurate.

Many people do not measure their blood pressure accurately due to strenuous exercise. Many people go to the hospital to measure their blood pressure in a panic, but this practice is wrong, which will affect the results of the measurement. <>

You can rest for a while and wait until you are back to your normal state before measuring your blood pressure. Before measuring blood pressure, you should not smoke, nor drink strong tea, coffee and other foods, these foods contain caffeine to speed up blood circulation, resulting in increased pressure in blood vessels, which will affect the accuracy of the value. Before measuring blood pressure, you can sit still and rest for 5 minutes to calm your mood and let the blood flow, so that the blood pressure measurement is more accurate.

Both the left and right hands should be measured for more accuracy. There should be some differences between the measurement results of the two, after all, it is related to people's daily usage habits. Generally, people who use their right hand regularly have higher blood pressure in their right hand.

It is best to measure blood pressure on the right hand. The blood pressure measurement in the right hand is higher than that in the left hand, and the blood vessels in the left hand are lower than in the right hand, so the blood pressure should be measured in the arm with the highest value.

Be sure to choose your left hand when measuring your blood pressure. The difference is. The measurement results are not the same. This is due to the fact that the left hand is closer to the heart, and the blood pressure measured by the left hand is more standard, and there will be no problems and errors.

For people who are accustomed to using the right hand or the left hand, the blood pressure of the arm can be 5mmHg higher than that of the opposite side, but it does not affect the determination of hypertension, when the patient measures blood pressure for the first time, usually measures both hands, and then measures the side with higher blood pressure, the blood pressure of the left and right hands is indeed different, and the difference is very large, such as more than 20mmHg, it is necessary to check whether it is Takayasu's arteritis, vascular occlusion, etc., and professionals need to check by CT or enhanced CT.
