Claim One:
1. A device for mapping in vivo electrical activity of a heart, comprising: an imaging unit which generates an anatomical reference image comprising an in vivo physical image of a heart disposed in a patient; a catheter carrying at least one electrode for sensing intracardiac electrical activity, said catheter being adapted for insertion into a heart; signal processing means for determining activation times, from electrical activity sensed by said at least one electrode, in relation to a reference time for electrical activity at different points in a heart; means for generating a graphic image showing said activation times at said different points in the heart and for superimposing said graphic image onto said anatomical reference image; reference means for inserting at least one reference point into said anatomical reference image; and setting means for aligning said graphic image with said anatomical reference image dependent on said reference point.
