A disposable electrode patch for medical purposes comprises a flexible, elongated substrate with a first and a second surface, a first adhesive material disposed on a first adhesive area at a first end of the first surface, and a second adhesive material disposed on a second adhesive area at a second end of the first surface. Electrodes are arranged between the first and second adhesive areas on the first surface of the substrate. In use, the electrode patch is folded around a body part in such a way that the electrodes on the first surface make contact with the skin of the body part, while the first and second adhesive areas of the first surface are pinched together to form a stable assembly surrounding the body part.
