Abstract

The present invention concerns a Medical system tor mapping of action potential data comprising an elongated medical mapping device (1) suitable for intravascular insertion having an electrode assembly (80) located at a distal portion (3) of the mapping device (1), a data processing and control unit (15) for processing data received from the mapping device (1), the data processing and control unit including a model generator for visualizing a 3-dimensional heart model based on one of electrical navigation system, MRI or CT scan data of a heart, a data output unit (16) for displaying both the 3-dimensional heart model and the processed data of the mapping device (1) simultaneously in a single visualization, wherein the model generator is configured to structure 3D scan data of the heart into 6 directions (a, b, c, d, e or 0 of a cube, each direction is associated with a separate Cartesian coordinate system with X(a, b, c, d, e or f), Y(a, b, c, d, e or f), Z(a, b, c, d, e or f) coordinates, wherein for assigning each 3D scan data point to one of the 6 directions (a, b, c, d, e or f) the following 6 true or false tests are applied: Formula (I), wherein max indicates the maximum leg length of the respective X, Y or Z axis and wherein mes indicates the measured value of a scanned data point, and wherein the data point is assigned to the direction (a, b, c, d, e or f) for which the test outcome is true.
