REAL-TIME SIGNAL COMPARISON TO GUIDE ABLATION CATHETER TO THE TARGET LOCATION

摘要

A catheter system includes a plurality of mapping electrodes, an electrode movable relative to the plurality of mapping electrodes, and a guidance system coupled to the plurality of mapping electrodes and the ablation electrode. The guidance system is configured to receive signals associated with intrinsic cardiac activity sensed by the plurality of mapping electrodes and the movable electrode, and to correlate in real-time the intrinsic cardiac activity sensed by the movable electrode with the intrinsic cardiac activity sensed by the plurality of mapping electrodes based on the signals received by the plurality of mapping electrodes and movable electrode to determine a location of the movable electrode with respect to the plurality of mapping electrodes.
