Abstract
A condition, such as an electrical property, of a chamber of a heart is surveyed with a catheter having a condition sensor at its distal tip. A method for surveying the chamber includes 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 including a representation of the catheter distal tip in the chamber, displaying a superposition of the topographical information extracted from 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 includes marking the display of the superimposed image to identify the points on the chamber at which the condition information was acquired.
