Hypertension simply means high bloo

Hypertension simply means high blood pressure. As a normal heart pumps blood through the body, a certain degree of pressure is excreted against the blood vessels. With each beat of the left ventricle, a wave of pressure starts at the heart and travels along the arteries. This wave is called the pulse. The pulse can be felt on any arteries that are close to the surface of the body, such as on the wrist, the sides of the throat and the temple. The pulse results from the blood pressure. The blood pressure at the moment of contraction is the systolic pressure; it should normally be sufficient to displace about 120 mm. mercury in a glass tube. The blood pressure at the moment of relaxation of the heart is the diastolic pressure; it normally displaces about 80 mm. of mercury. Blood pressure readings, which are frequently taken during a general physical examination are presented as a ratio of the first figure over the second.
Most physiologists have consider a blood pressure reading of 150/90 as excessive. This can be considered a useful definition of high blood pressure.

Hypertension is very common. It is believed that about one out of every five American has suffers from it and that about 13 per cent of all deaths are a direct result of it. Hypertension has become more common with increasing age and affect men about twice as often as women.

In about 90 per cent of the known cases, it has been described as essential hypertension, a hereditary condition. In other cases it may be due to the removal of a kidney, kidney disease, excessive narrowing of the arteries, hormone imbalance, or excessive salt in the diet.

It has been known for many years that hypertension is damaging for two reasons: 1) it puts an excess work load on the heart and the left ventricle in particular; 2) the arteries may be damaged by excessive pressure. A hypertensive patient tends to develop cardiovascular ailments much sooner than a person who has not suffered from hypertension.

This high blood pressure in the arteries causes a hardening (sclerosis) of blood vessels all over the body. The vessels become weakened; clots tend to form in them much more easily; some vessels rupture and haemorrhage. For centuries haemorrhage in the vessels of the brain (cerebral haemorrhage) and vessels of the kidneys has been known to be particularly destructive.

Гипертензия означает высокое кровяное давление. Как нормальный сердце перекачивает кровь по всему телу, определенная степень давления экскретируется против кровеносных сосудов. С каждым ударом левого желудочка волна давления начинается в сердце и проходит вдоль артерии. Эта волна называется пульс. Пульс может ощущаться на артериях, которые находятся близко к поверхности тела, такие как на запястье, стороны горла и храм. Результаты импульса от кровяного давления. Кровяное давление в момент спада является систолическое давление; как правило, должно быть достаточно для подмены около 120 мм. ртуть в стеклянной трубки. Кровяное давление в момент расслабления сердца является диастолического давления; Обычно он вытесняет около 80 мм. ртути. Показания артериального давления, которые часто принимаются во время общей физической экспертизы представляются как отношение первой фигуры над вторым. Большинство физиологов есть считают чтение кровяное давление 150/90 как чрезмерное. Это может считаться полезным определение высокого кровяного давления.Гипертония является очень распространенным явлением. Считается, что примерно один из каждые пять американских имеет страдает от него, и что около 13% всех смертей являются прямым результатом его. Гипертензия стало более распространенным с увеличением возраста и влияет на мужчин о вдвое чаще, как женщины.In about 90 per cent of the known cases, it has been described as essential hypertension, a hereditary condition.
