Abstract

The observations were carried out in 51 healthy volunteers (26 men and 25 women) who underwent passive orthotest with the registration of thoracic impedance (TI). It was found that women had a higher index of TI both in rest and in dynamics of the performance of the orthostatic test than men. In 10 subjects the increase of TI in orthostasis was higher than 15% that can be supposed to be a criterion of the pathological drop of the venous return. The TI dynamics in performing the orthotest was quicker than changes in AP and the appearance of complains can be taken for a preclinical symptom of latent volume disturbances in the orthostatic regulation that has an important diagnostic value.
