Abstract
A multichannel impedance and one lead electrocardiographic recording system has been developed. The impedance measurement unit is built using a four-electrode technique. It consists of a sinusoidal, 40 kHz, current source and five measurement channels. Circumferential current electrodes have been located at a neck and an abdomen. Voltagemeasurement disk electrodes formed five two-electrode measurement ports. The impedance change waveforms (ICG) have been recorded simultaneously with ECG. The ICG waveforms have been analyzed using Principal Component Analysis (PCA). The examinations have been done for different ports configurations in relation to the heart. A dependence of obtained components on ports configurations has been found. Similar results have been obtained when examining healthy (test) persons.
