Systolic and diastolic pressure

By arterial pressure means the volume of blood pumped by the heart per unit time. The highest blood pressure is observed during its exit from the cardiac left ventricle. In the arteries, blood pressure is slightly less. When moving to the capillaries, it is further reduced. Venous blood pressure is considered the lowest, especially at the entrance of the right atrium. In different parts of our body, there is a different degree of blood pressure. What is systolic and diastolic pressure? What is the difference between them?

Systolic blood pressure is the upper figure of this important parameter. This indicator indicates the level of pressure at the moment when the heart muscle contracts , as a result of which blood is pushed into the arteries. This indication is completely dependent on the power of the contractions of the heart muscle.

In medicine, diastolic blood pressure is considered the lower figure of the parameter. This indicator reflects the pressure parameters during complete relaxation of the heart muscle. It should be noted that this pressure is the minimum pressure in the arteries. The parameters of the amplitude of fluctuations in blood pressure decrease as the blood flow moves through all the vessels. An important point is that the capillary and venous pressure is almost independent of the phases of the cardiac cycle.

Systolic and diastolic pressure have optimal values and critical values. So, the norm of blood pressure is considered to be indicators that are within 120/80 mm Hg. The optimal difference between the upper and lower value of this indicator is the ratio of 30/40. This difference is usually called pulse pressure.

Systolic and diastolic pressure are very important medical indicators that indicate the general state of human health. So, in some people there is a periodic increase in blood pressure relative to normal. Such a symptom is called arterial hypertension. A stable value of the arterial pressure index below the norm is called arterial hypotension. This deviation from the norm can lead to a disease with hypertension or hypotension.

Systolic and diastolic pressure in people over 50 years of age deserves careful diagnosis, because at this age people are especially susceptible to the development of various diseases of the cardiovascular system. Of these two parameters, elderly people should carefully monitor precisely the indices of systolic pressure. The maximum permissible limit of normal pressure for people aged is 140/90 mm Hg. Usually, indicators below this level are considered normal, but if the diastolic pressure, regardless of age, has exceeded the value of 90 mm Hg, a cause for serious concern arises.

Arterial pressure should ideally correspond to the norm, since any deviation of this or that parameter from the normal value indicates the development of some disease. If there are any abnormalities in blood pressure indicators, it is advisable to consult a doctor right away. Only a specialist will be able to accurately determine the cause of such a deviation and the methods for its elimination.

Since the heart is inherently a muscle that shrinks and decompresses throughout our life, it can gradually wear out. Systolic and diastolic pressure reflects the general condition of the heart muscle, and any irregularities in her work will be immediately noticeable due to these important indicators.
