Performance of impedance cardiograph for measuring heart rate and body fluids
Impedance cardiographic system to measure cardiac output and cardiovascular functions
Four-electrode impedance plethysmograph measures ventricular stroke volume of cardiac output of humans. The instrument is automatic, operates with only one recording channel, and minimizes patient discomfort.
