METHODS AND SYSTEMS FOR MINIMIZING AND TREATING CARDIAC FIBRILLATION

摘要

Methods and systems for using feedback to minimize and treat cardiac fibrillation in a patient, includes generating a map of one or more measurements indicative of a number and distribution of electrical circuit cores for a duration across a cardiac tissue substrate in the patient's heart in response to electrical activity, defining an optimal placement of at least one ablation lesion in the cardiac tissue substrate; applying ablation lesion therapy based on the optimal placement; determining whether the ablation lesion therapy minimized or treated cardiac fibrillation; if therapy is determined to have minimized or treated cardiac fibrillation, assessing fibrillogenicity of the cardiac tissue substrate to determine whether fibrillogenicity is below a predetermined threshold; and if therapy is determined to have not minimized or treated cardiac fibrillation, repeating the steps of generating, defining, applying, and determining until ablation lesion therapy minimizes or treats cardiac fibrillation.

1. A method for using feedback to at least one of minimize and treat cardiac fibrillation in a patient, comprising:
obtaining a map of one or more measurements indicative of a number of electrical circuit cores and distribution of the electrical circuit cores for a duration across a cardiac tissue substrate in the patient's heart in response to electrical activity in the cardiac tissue substrate, said map being registered onto a representation of the patient's heart; defining an optimal placement of at least one ablation lesion in the cardiac tissue substrate; applying ablation lesion therapy based on the optimal placement of the at least one ablation lesion; determining whether the ablation lesion therapy at least one of minimized and treated cardiac fibrillation; if the ablation lesion therapy is determined to have not at least one of minimized and treated cardiac fibrillation, repeating the steps of generating, defining, applying, and determining until ablation lesion therapy at least one of minimizes and treats cardiac fibrillation.
