ABSTRACT:
Monitoring intracardiac ablation progress in near real time is accomplished by evaluating capture of a pacing signal while ablation energy is concurrently directed to a target site. Sufficiency of ablation is indicated by failure of signal capture at a maximum predetermined pacing voltage. A common electrode in a cardiac catheter is simultaneously used to test pacing capture and to deliver ablation energy.
