[Role of changes in blood volume and linear velocity in the formation of pulsatile electrical impedance oscillations]. 1981

B I Mazhbich, and P V Matveev, and M D Roĭfman

Measurements of the module of the blood electrical impedance by means of tetrapolar rheography method with the electrodes placed both outside and inside of the pig aortical preparation revealed the vessel blood volume oscillations dependence on the blood flow velocity, the latter increment relation to the pulsatile impedance changes. Under life conditions the pulsatile oscillations of the blood flow electrical impedance were fully dependent on the vessel volume changes.
