A catheter (20) for measuring physiological signals in a heart comprises a structure at a distal end of the catheter (20) wherein the structure has a plurality of arms (80, 82, 84), an electrode (26, 28, 30) fixed to each arm (80, 82, 84) and a device for generating position information located on each arm (80, 82, 84). The arms (80, 82, 84) are located near the long axis of the catheter (20) during insertion of the catheter (20) within a heart and the arms (80, 82, 84) are spreadable apart and away from the long axis of the catheter (20) when the structure is within the heart. <IMAGE> |
