Rheography liver

Method rheography based on the fact that the blood better than other fabrics, conducts high-frequency current. So changes of electric resistance between two electrodes placed over the body, reflect fluctuations his blood during the cardiac cycle (A. A. Cedars, 1941). Volume liver changes depending on the state of the vascular wall, blood flow systems of the portal vein and hepatic artery, the blood flow through the system of the hepatic veins, which in turn is determined by the nature and degree of morphological changes in the body.
Reogepatografiya can be used for diagnostics of chronic hepatitis and cirrhosis, segregation of jaundice, assessment of the degree of severity of the disease, control of medicines and evaluation of recovery (A. S. Loginov and 10. So Pushkar, 1962; A. S. Loginov, 1969; P. E. Krel, 1969, 1970; E. P. Fursova, 1970, and others).
The recording is done with the help of rheography, connected to the electrocardiograph. Normal rogramme liver consists of the main systolic wave, the top of which corresponds to the T wave ECG and begins after 0.1-0,18 seconds after ECG zubza Q. The duration of the rise in systolic wave of 0.12 to 0.3 seconds.
Geographical index, which expresses the ratio of the amplitude of rogramme to gauge the pulse must be above unity (A. S. Loginov, 1970). The main systolic wave can precede little presistolic wave. Third, posteitaliane, wave superimposed on the downside knee systolic wave. In the diffuse liver diseases amplitude rogramme and eographically index decrease, the duration of the rise in systolic wave is reduced.
