Abstract

A method of assessing lesion formation associated with pulsed field ablation (PFA) therapy delivered to a selected location by a PFA catheter includes measuring pre-therapy impedance using one or more electrodes located on the catheter and delivering a first PFA application. An intra-therapy/post-therapy impedance is measured using the one or more electrodes located on the catheter and a PFA index (PI) metric is calculated based on a model that combines the measured pre-therapy impedance, the measured intra-therapy/post-therapy impedance, and attributes of the first PFA application delivered, wherein the PI metric is representative of a likelihood that the lesion has reached a selected size.
