Weakness and failure of the left ventricular lead to stagnation of blood with increasing pressure in the left atrium and the pulmonary circulation. Under the influence of high pressure in a small circle and the left atrium during diastole the left ventricle is filled with hard. Moreover, if it is reduced performance is not strong, it can increase your cardiac output 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 the evils of the left ventricle, and hypertension, this first-stage heart failure, and at the same time and payment can be kept for a long time and lead to hypertrophy and tonogennomu expansion of the right ventricle. The further held that state sooner exhausted the reserve forces and compensatory factors of the right heart, the more noticeable develop venous hypertension in the systemic circulation, congestion of the liver, abdominal organs, swelling of the lower extremities, ascites, and all other consequences.
When it is failure of the right ventricle, 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 heart failure.
- Venous blood of the left ventricle
According to new data in the literature, the venous blood of the left ventricle flows mainly to the coronary sinus, the right is more - the smallest veins. There is every reason to believe that the different functional states, primarily under the influence of pressure changes in the different chambers of the heart, and in different segments of the coronary circulation, blood flow in the vessels Vessena-Tebeziya can [...]
- Effective treatment of patients with essential hypertension 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) a medical complex - Climate + mineral water "Turshsu" inside and 2) a separate bath and turshsuinskoy medical complex - Climate + mineral water "Turshsu" inside + course turshsuinskih baths. Of course, asking these questions is [...]
- Communication between the
It should be noted that among all organs, secrete certain hormones, there is mutual contact. Through this connection, some cancer affect the other products of these glands are allocated in proportion to the need of the organism and are actively involved in 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 walls of blood vessels and blood allow at any given period of time to maintain optimal blood pressure, that is. [...]
- Disruption of the neurohormonal
Neurohormonal dysfunction, blood pressure regulating mechanisms can lead to hypotension or hypertension, and ultimately - to hypertension. If under the influence of neural factors primarily arises increase vascular tone, then for the future development of hypertension requires a number of additional factors. For the development of hypertension are needed along with the disturbance of the cortical dynamics of changes in the [...]
