Weakness and failure of the left ventricle leads to stagnation of blood pressure increases in the left atrium and the pulmonary circulation. Under the influence of high pressure in the pulmonary and left atrium during diastole the left ventricle fills hard. Moreover, if his performance is not greatly reduced, it may increase their minute volume to normal, so that a balance is reached with the normal blood circulation in the systemic circulation, but high blood pressure in the small. When defects and left ventricular hypertension, this first stage of heart failure and at the same time and compensation can be kept for a long time and lead to hypertrophy and tonogennomu expansion of the right ventricle. The further held that state faster than exhausted the reserve forces and compensatory factors right heart, the more noticeable develop venous hypertension in the systemic circulation, the stagnation of the liver, abdominal organs, swelling of the lower extremities, ascites, and all other consequences.
When it comes right ventricular failure, liver, blood vessels and other organs that are closer to the heart, the first overflow of venous blood. They shall be part of the blood. Especially crowded blood liver deposited about 1.5 liters of blood (hepatic veins have no valves, and thus they do not prevent backflow of venous blood into the liver). Ver these phenomena are of great importance in compensatory cardiac failure.

- Venous blood of the left ventricle
According to new data in the literature, the venous blood of the left ventricle flows mainly through the coronary sinus, really - by the smallest veins. There is every reason to think that under different functional states, primarily under the influence of pressure changes in the different chambers of the heart, and in the different segments of the coronary circulation, blood flow in the vessels Vessena-Tebeziya can [...]
- The effectiveness of treatment of hypertensive patients resort factors Turshsu
We set out to study the effectiveness of the treatment of patients suffering from hypertension, different sets of medical factors Turshsu. To do this, studied the effectiveness of: 1) the medical complex - Climate + mineral water "Turshsu" inside, and 2) a separate bath and turshsuinskoy medical complex - Climate + mineral water "Turshsu" inside + course turshsuinskih baths. Certainly, asking these questions is [...]
- Communication between authorities
It should be noted that among all the bodies that release certain hormones, there is a mutual relationship. Through this connection, some cancer affect other products of these glands are allocated in proportion to the need of the body and are actively involved in the regulatory mechanisms. So, do not doubt the influence of pituitary adrenal and other glands, and is not excluded [...]
- Determination of peripheral vascular tone
Peripheral vascular tone is determined ostsillografichsskim and plethysmographic methods. As is known, the blood pressure is the pressure that is experiencing blood located in the arterial network. Hence it is clear that the state of the arterial network, its filled with blood, the impact of various external and internal factors on the blood vessel walls and allow in any given period of time to maintain optimal blood pressure, that is. [...]
- Neurohormonal dysfunction
Neurohormonal dysfunction, the mechanisms regulating blood pressure can lead to hypotension or hypertension, and ultimately - to hypertension. If under the influence of neural factors primarily arises increase vascular tone, the further development of essential hypertension requires a number of additional factors. For the development of essential hypertension are needed, along with impaired cortical dynamics changes from the side [...]
