Abstract
A device for mapping electrical activity in a patient's heart, has an imaging unit, such as a fluoroscopic imaging unit, for generating a physical in vivo image of a patient's heart as an anatomical reference image, an electrode catheter, with at least one electrode for sensing intracardiac electrical activity, for insertion into a patient's heart, and signal processing equipment for determining activation times, from sensed electrical activity, in relation to a reference time for electrical activity at different points in the heart, and for generating a graphic image showing the activation times at different points in the heart and superimposing this graphic image onto the anatomical image. An arrangement is further provided for inserting at least one reference point into the anatomical image, and a setting unit moves the graphic image in relation to the reference image with the aid of the reference point.
