The formation of blood vessel tone is affected by multiple factors. First and foremost, it is formed the internal pressure on the walls. The second factor is externally-vascular nervous regulation. Together, these processes combine in the concept of blood pressure. For healthy people there is no official standard – 120/80. But in fact values are not static. These figures are plastic and slightly change every second.
The First indicator reflects the kind of intensive blood pressure on the vascular wall during contraction of the heart. In this case we speak of the upper or systolic pressure. It shows it reduces the heart muscle. Education systolic blood pressure in the presence of large vessels such as the aorta. Normal values are in the range 120-130 mm. the numbers depend on several factors: the extensibility of the vascular walls, stroke volume in the left ventricle, the maximum speed of exile.
Diastolic (lower) pressure is determined upon relaxation of cardiac muscle. It also established normal values – 80 to 85 mm. Diastolic pressure reflects the resistance experienced, passing through the vessels, blood. Its formation occurs at the time of closure of the aortic valve. At this time the blood to flow back to the heart cannot, and it, in turn, is filled with blood, enriched with oxygen, for subsequent reduction.
The Mathematical difference of the upper and lower pressure is called the "pulse rate". The normal level is in the range of 30-40 mm. However, experts draw attention to the fact that of great importance is the General condition of the person. Regardless of the numbers, each can have its own pressure.

This term is used by cardiologists in the designation of such indicators, with which the person feels normal. Optional this is the traditional and accepted norm. When the HELL is 120 on 80, a man called "normotonics". Those who have all the time there is a value in the range of 140/90 are considered hypertensive. The wellbeing of good people. If the values are within the range of ninety to sixty, such a state is defined as hypotension. But for some people, and these figures are the norm. The value of the upper and lower pressure deviating from the classical, is not always a sign of any abnormalities. So, for example, athletes who stopped a heavy load, working marked hypotension. At the same time the General health of these people is quite satisfactory.
What is the pressure of the upper and lower will be for the normal person, largely depends on the way of his life, the presence or absence of bad habits, diet, stress. In practice there are known cases stabilize readings to normal without taking medication. It was enough to eliminate errors in diet, change the activity.
I Should say that modern doctors are moving away from the use of "pharmacological adjustment" of a BP level under the old standards. Doctors recognize and this is proved by numerous observations that people can feel due to the deviations in numbers from the regulations. So, for the elderly is characteristic of the conservative pressure. However, it is generally static, which does not have a significant negative impact on the condition of the people in age. In this case, according to the doctors, intake of antihypertensive drugs unjustified and inappropriate. Based on past experience, experts come to the conclusion that the forced change of tone only contributes to loosening of the cardiovascular system.
An Important role in the assessment of the General condition of the patient plays a pulse pressure difference. Between the upper and lower pressure should be a number in the range of 40-50. This rate is considered optimal. However, there is a wider range-from 30 to 50. The pulse rate may be small. High pressure and high top indicate the overload of the heart. While there is rapid heartbeat (tachycardia). This suggests that the body works hard. Big difference in pressure indicates, on the contrary, the slow motion activity of the heart. Bradycardia developing in this state, provoking tissue hypoxia and Central nervous system. In other words, when the pulse rate is greater than 50 in the process of pumping blood, the heart muscle gets tired. This can lead to its rapid deterioration.
If notes other pressure difference (between upper and lower pressure is less than 30), it says about muscle weakness. In this regard, to tissues not getting enough oxygen. Hypoxia primarily affects the activity of the brain: patients marked fainting, nausea, dizziness.
It Should be noted that in the process of pressure measurement selected devices (electronic in particular) can give errors. Experts recommend (for accuracy) to use mechanical blood pressure monitors. Indicators removed first one then the second hand.There is a difference of pressure. Between the upper and lower pressure difference on the second hand should be no more than ten units.
Half an hour before the procedure, you must refrain from eating, Smoking, physical activity. You should also eliminate temperature swings. Immediately before the measurements you need to relax, a few minutes to sit quietly. The patient should remain in a sitting position, and his back is to be supported. This is because any load is accompanied by an immediate increase in AD.
The horizontal position of the hand placed along the body, while it should be slightly raised to the line of the middle of the chest (you can put something, a pillow for example). It is not recommended to talk and to make sudden movements during the measurement.
Between the top and bottom pressure changes, as mentioned above, may be minor, but could be significant. And in that and in other case it adversely affects the human condition. The slight variations in numbers are often the result of violations of the emotional background. the lower High blood pressure and high top indicate lack of elasticity of blood vessels, expansion of the myocardium, atherosclerosis, which, in turn, provokes quite a lot of negative consequences. With the increase of pulse rate, there is always a decrease in cerebral perfusion pressure. This is the name of the force responsible for pushing blood through the vessels of the brain. This condition, in turn, causes hypoxia.
A Significant pressure difference (between the top and bottom pressure deviation from 50 units) professionals is regarded as a quite dangerous symptom. In particular, it can indicate a possible stroke or heart attack. Hypotension, as a rule, somnolence, tremor, syncope. Patients often become dizzy.
In this case, increased pulse indicators can indicate the presence of TB lesions of the digestive and biliary systems. In addition, such deviations may indicate an increase in VD (intracranial pressure), heart block, anemia. Patients there is a concern developing endocarditis. In addition, conditions are accompanied by increased stiffness in large arteries. In some cases a small pressure difference (between upper and lower pressure of less than thirty units) tells about the stenosis of the arteries. Fluctuations often accompany pregnancy.
Both are bad. Often in patients with reduced AD manifest the same symptoms as high. In particular, there is flies flashing or sparks before the eyes, headaches and dizziness, chest pain. In some cases, you may be nausea until vomiting, weakness.
The Lack of necessary and timely care can lead to serious consequences. For example, in high pressure high risk of hypertensive crisis, which can provoke rupture of blood vessels, cerebral disorders up to paralysis.
If hypotension is likely atrophic brain damage, cardiac arrest, violation of visual functions. The greatest danger in this case is a developing body resistance to the introduction of cardiotonics. Attack sharp decline or increase in blood pressure may occur suddenly. The person often loses consciousness. In this case, you need emergency assistance.
Ideal performance in medicine. But there is a formula by which to calculate the optimal ratio. The bottom AD is multiplied by eleven, and then divided by the diastolic index. If you get a number close to seven, it is considered that the level optimal for the human condition. These calculations can be applied from the age of twenty years.
Experts remind that any, even the smallest, the difference between pressure may indicate irregularities in the body. This is especially true of people whose age is over forty. In this regard, in order to avoid dangerous consequences should not delay visiting a cardiologist.
Parameters can have an impact on virtually all aspects of life. This diet and stress, psycho-emotional background, bad habits, fatigue, medication. Observing simple rules of power, controlling the concentration of cholesterol, taking vitamins, avoiding stressful situations, a person can maintain a normal condition of the heart and blood vessels.
