separation from one another is reduced from 30 mm to 3 mm in this way the strap or lug formed thereby may be attached to a conventional terminal clip and the design of a special clip becomes unnecessary thus reducing costs in order to prevent adhesion to the terminal clip during measurement the contact strips are non adhesive in the area of the connection straps the top side of support surface 1 shown in fig3 and contact strips 2 a 2 b are protected in storage by a conventional tear off foil not shown to prevent the contacts and adhesive surfaces from dirt and damage this foil must be removed before use with such electrodes according to the invention it is possible to create an alternating field over the patient 39 s chest that is considerably more homogeneous and stable than with the prior art with the result that the sensitivity reproducibility and precision of the measurements are significantly increased for example with the measuring arrangement shown in fig2 it is possible to work with an alternating field frequency of only 40 khz and a current strength of only 350 u03bca this enables the detection threshold of the measured voltage signals to be lowered to the range of 0 01 u03bc while the measurement values are available within a few seconds by contrast according to the prior art it was necessary to wait up to a minute before a clear signal was obtained moreover a measuring arrangement of such kind using the electrodes according to the invention is certifiable for u201c cardiac flow cf u201d applications for which a current strength not exceeding 0 4 ma may be applied according to iso or en.
