ABSTRACT:
A multiple electrode array senses electrical events in heart tissue at different orientations in a localized region. First, second, and third electrode elements are spaced apart along different axes. The electrodes are electrically isolated from each other. The spaced apart and electrically isolated electrodes sense multiple bipolar signals measured along the different axes. The electrode array can, without changing position, continuously record multiple electrical events at different relative orientations within a localized area. The spacing and orientation of electrodes on the array permit the physician to detect a small volume signal (like one associated with an accessory pathway) and to differentiate it from nearby large volume signals (like those associated with atrial and ventricular potentials).
