Abstract
A system for monitoring electrical activity at an ablation site where the system includes an ablation device having an elongate, flexible shaft and a distal treatment section for delivering ablation energy to target tissue, a first electrode mounted on the distal treatment section, a second electrode mounted on the distal treatment section where the second electrode is spaced from the first electrode a distance (D1), a plurality of conducting elements extending along the distal treatment section and being connected to the first electrode and the second electrode, the plurality of conducting elements for connecting the first electrode and the second electrode to an electrophysiological recording system, a processing device programmed to receive the electrical information from the ablation site from the first electrode and the second electrode, and an electrophysiological recording system.
