Abstract: An electrode arrangement provides an electrode line (10) carrying at least a first fixing element (16) which is designed to fix the electrode line to body tissue, especially the myocardium of a heart, and which is arranged at a spacing relative to the distal end (12) of the electrode line (10), wherein the first fixing element (16) is fixedly connected to the electrode line (10) and has a free first end (40) which has a component of extension in a direction tangential with respect to the electrode line (10) and which is of such a configuration that the first fixing element (16) penetrates into body tissue that is adjacent to the electrode line in the situation of use by a rotary movement of the electrode line (10) about the longitudinal axis thereof.

Abstract: An electrode arrangement (10) comprising a first electrode cable (12) which is to be inserted into the coronary sinus and which has an electrode conductor (32) and at least one electrode (38, 40) for outputting and/or receiving electrical signals in the coronary sinus. Longitudinally slidably guidable in the lumen of the first electrode cable (12) at least in a longitudinal portion-wise manner is a second electrode cable (14) which can issue from the first electrode cable through an opening (52) at the distal end thereof and which is adapted for insertion into a cardiac vein which opens into the coronary sinus.
