[Thoracic electric bioimpedance].
So far there was, no simple non-invasive method for the assessment of the minute. Rheoplethysmographic methods developed in the seventies did not give reliable results. The submitted paper presents a new quantitative rheople-thysmographic method - thoracic electric bioimpedance. The authors explain the technique, defines the assessed parameters and evaluates their scatter according to data reported in the literature. They explain from the physiological aspect the possible development of some errors when applying the method. The method of thoracic electric bioimpedance makes it possible to assess clinically valuable haemodynamic parameters comparable with corresponding values obtained by pretentious and invasive methods.
