Abstract

An electrode assembly for medical purposes comprises a to first electrode 11electrically connected to a first connecting line 15, a second electrode 12electrically connected to a second connecting line 16, and a third electrode 13electrically connected to a third connecting line 17. The first, second and third electrodes are GI arranged in a single patch 14. The shape or area of the second electrode is different from the shape or area of the first and third electrodes. The first, second and third connection lines may be coded by visible or tactile coding means.
