Abstract
The present disclosure provides systems and methods for determining a proposed ablation site in a cardiac chamber. A system includes an implanted device configured to record a plurality of intracardiac electrogram (IEGM) couples, and a mapping and ablation system communicatively coupled to the implanted device. The mapping and ablation system is configured to receive the recorded plurality of IEGM couples from the implanted device, calculate a parameter for each of the plurality of IEGM couples, determine, based on the calculated parameters, an area of origin for each IEGM couple, and determine an intersection between the determined areas of origin, wherein the intersection represents the proposed ablation site in the cardiac chamber.
