<p>Methods and systems for preparing electroanatomic maps of the heart operate using a probe that has been inserted into a heart chamber by emitting electrical calibration signals from external locations that are outside the subjects body, receiving the calibration signals in a plurality of intracardiac electrodes on the probe, and determining functional relationships between the emitted calibration signals and the received calibration signals. Thereafter, electrophysiological signals from respective origins in the heart are detected in the external locations, and the functional relationships are applied to the detected electrophysiological signals to calculate intracardiac potentials at the respective origins.</p> |
