FIELD: medicine; medical engineering.
SUBSTANCE: method involves representing and calculating blood volume ejected by the left ventricle (LSV) or one ejected by the right ventricle (RSV) as function of at least one of area under pressure plot indices and as function of hydraulic impedance. The heart stroke volume Q is calculated from formula Q=LSV*HR (or Q=RSV*HR), where HR is the heart beat rate frequency. The device provides both processing signals and making calculations.
EFFECT: high reliability of measurements.
