PROBLEM TO BE SOLVED: To provide a novel device and method for making an electrical map of the ventricles speedily by using a catheter including the main body part with a base end part and a tip part. SOLUTION: The tip part of the catheter has a tip position, a non-contact electrode array with the base end part and the tip part, and at least one position sensor. Preferably, two position sensors are used. The first sensor is located preferably to the base end side rather than the tip position of the catheter, and the second sensor is located preferably to the base end side rather than the base end part of the non-contact electrode array. |
