The impedance rheography as a method of measurement and recording of electrical impedance and its changes in a body segment is widely used in research and medical practice. Several types, single or multichannel, analog or digital impedance rheographs were developed at Warsaw University of Technology. A digital impedance rheograph has been recently designed for measurement of impedance modulus (...) and its changes (...) of body segment or tissue sequent simultaneously with ECG signal. The designed rheographs were positively tested technically and clinically. In this article is presented the clinical application of impedance rheography for study of systemic and pulmonary blood flow in two different groups of patients with several cardiac abnormalities or after therapeutic procedures. The investigation of systemic blood circulation was done on group of 20 patients with cardiac arrhythmia (15 cardioverted and 5 cardiostimulated patients). The pulmonary blood circulation was studied on 20 healthy and 26 patients: 8 with isolated pulmonary stenosis and 18 with Fallot syndrome. The findings show that impedance method allows to detect and assess these abnormalities.
