Blood Pressure Systolic

Systole blood pressure is the blood pressure at the moment of maximum ejection of blood by the heart during contraction of the heart muscle. This indicator is calculated as the ratio of pressure (in millimeters of mercury) to heart rate, one second is taken as a unit. When measuring systole blood pressure, the first beat of the tonometer must be accurately noted after it reaches its maximum value during contraction of the heart muscle. Then the number is written down. The normal systolic blood pressure is 110 – 130 mmHg. Art. Pressure values ​​above 180 mm are life-threatening. rt. Art., but if the heart works normally, then their dangerous and dangerous levels are much lower.

Arterial systoles begin simultaneously and almost instantly. By the beginning of the systole phase, the arteries are maximally compressed and relaxed. If a person dies from a cerebral hemorrhage, the cause may be rupture of blood vessels, which causes a sharp decrease in pressure. For some patients this may be relevant. In old people, increased systolic blood pressure significantly increases the risk of cerebral bleeding, but the critical level is at least 220-230 mm. RT. Art. Normal blood pressure is 120/80 or 140/90.
