摘要： The present invention provides a readable storage medium, an ablation system and an electronic device. The readable storage medium having a computer program stored thereon, when the computer program is executed by a processor to perform the steps of: controlling an ablation catheter to apply pulsed energy to target tissue and determining electric field energy and resistance during ablation process; calculating a theoretical ablation lesion size according to the electric field energy and the resistance; determining whether the difference between the theoretical ablation lesion size and a target ablation lesion size is within a first predetermined range; if so, controlling the ablation catheter to stop applying pulsed energy to the target tissue; and if not, controlling the ablation catheter to continue applying pulsed energy to the target tissue, until the difference between theoretical and target ablation lesion sizes is within the first predetermined range. The present invention enables prediction of PFA efficacy, which can effectively enhance the success rate of a PFA procedure and avoid irreversible thermal damage from being caused to tissue.
