Abstract

The invention relates to a method for measuring the volume, the composition and the movement (HZV) of electroconductive body fluids, based on the electrical impedance of the body or a body segment, especially for performing electromechanocardiography (ELMEC) or impedance cardiography (IKG) measurements for determining hemodynamic parameters. According to said method, an alternating measuring current (52) of at least one frequency is introduced into the body (60, 70), and the impedance and temporal variations (AZ) thereof of essentially the same body segment through which the alternating measuring current flows are measured for at least two different measuring lengths (L, L2, L3, L4, L5), essentially in the longitudinal direction of the body.
