A method for intracardially surveying a condition such as an electrical property of a chamber of a heart with a catheter having a distal tip and a condition sensor contained therein. The method comprises the steps of acquiring a first image of the chamber containing topographical information, advancing the distal tip of the catheter into the chamber, acquiring a second image comprising a representation of the catheter distal tip in the chamber, displaying a superposition of topographical information acquired in the first image with the second image to generate a displayed superimposed image, acquiring condition information at a point on the chamber displayed on the superimposed image on or near the topographical information, and acquiring condition information at one or more additional points sufficient in number and spacing to permit the generation of a survey map of the condition in the chamber. The method preferably further comprises marking the display of the superimposed image to identify the points on the chamber at which the condition information was acquired.
