1. A method for localizing a source of electrical activity within a mass of body tissue, comprising:
- applying a predetermined electrical stimulus to a portion of the surface of the body tissue at a first location;
measuring an actual complementary response to said electrical stimulus at the surface of the body tissue at a second location spaced from said first location;
removing said predetermined electrical stimulus from said first location; and
measuring an actual complementary response to the source of electrical activity at the surface of the body tissue at substantially said second location.

Abstract
A method for localizing electrical activity in the body. A plurality of electrical devices apply a predetermined current (or voltage) to the surface of the body, and sense voltage (or current). The same electrical devices employed to sense voltage (or current) from sources of electrical activity within the body are also employed to sense voltage (or current) that results from the application of current (or voltage) by the other electrical devices. The voltages (or currents) sensed are used to characterize impedance within the body as well as to localize sources of the electrical activity.
