title: [Body impedance recording in the assessment of stroke volume].
abstract: The first derivative of the integral tetrapolar rheogram of the body, body impedance recording, was found to show changes in blood flow in the arterial compression chamber. Evidence was given for a close relation of the distance between the electrodes while recording an integral rheogram of the body and the examinees' height. The relation of the distance to the examinees' height was equal in males and females and proved to be lower than that previously applied. For calculation of the stroke blood volume from the body impedance recording, the Kubicek equation was proposed to be used by introducing the height of an examinee instead of the distance between measuring electrodes. There was a good coincidence of results while calculating the stroke volume by impedance recording and Doppler echocardiography.
