The disclosed electrode catheter includes: a catheter body (10); a control handle (20); catheter tip-end sections (31, 32, 33, 34); and ring-shaped electrodes, a plurality of which being attached to each catheter tip-end section. One ring-shaped electrode (41B) attached to the first catheter tip-end section (31) and one ring-shaped electrode (42C) attached to the second catheter tip-end section (32) are broader in width than the other ring-shaped electrodes (41c, 42b, 43b, 43c, 44b, 44c). The ring-shaped electrodes (41B and 42C), which are broader in width, are arranged at different positions on the respective catheter tip-end sections to which the same are attached. With the disclosed electrode catheter, it is possible to easily find out which catheter tip-end section and which position thereon the electrode specified on an X-ray image is attached to. |
