Abstract
The present invention is a system for three-dimensionally mapping a heart, comprising: a mapping catheter including three or more optical cores each of which has a plurality of FBGs disposed in the lengthwise direction of a catheter body, and a plurality of electrodes disposed in the lengthwise direction of the catheter body and exposed on the outer circumferential surface of the catheter body, wherein the electrodes make contact with the inner wall of the heart; and a mapping processor for calculating coordinates of the FBGs by wavelength information of reflected light received from the three or more optical cores, and calculating coordinates of the electrodes from the coordinates of the FBGs so as to build a three-dimensional shape of the heart by using a sample point at which the plurality of electrodes make contact.
