Abstract
An array of electrode sites are placed in a heart chamber. The shape of the chamber and the location of the electrodes is determined via impedance plethysmography. Electrical measurements taken from the electrode array and referenced to a surface contacting electrode is used to generate a three-dimensional map of electrical activity. A two-dimensional map of the electrical activity within the endocardial surface is also computed.
