Weakness and failure of the left ventricular lead to stagnation of blood pressure increases 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 fills hard. Moreover, if his performance is not much reduced, it can increase your cardiac output to normal, so that balance is restored to the normal circulation to the systemic circulation, but high blood pressure in the small. When the left ventricle and the evils of this first stage of hypertension 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 faster than exhausted the reserve forces and compensatory factors of the right heart, the greater 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 right ventricular failure, liver, blood vessels and other organs that are closer to the heart, the first overflow venous blood. They have deposited some of the blood. Especially crowded blood liver depositing about 1.5 liters of blood (the hepatic veins have no valves, and thus do not impede venous backflow of blood to the liver). Rev. 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 through the coronary sinus, right the same - to 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 vessels Vessena-Tebeziya can [...]
- Effectiveness of the 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. For this study 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 [...]
- Relationship between the
It should be noted that among all the bodies secrete certain hormones that 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 organism and are actively involved in regulatory mechanisms. So, there is no doubt the influence of pituitary and adrenal function of 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 allow blood at any given period of time to maintain optimal blood pressure, etc. [...]
- Neurohormonal dysfunction
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, the further 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 [...]
