SYSTEMS AND METHODS FOR DIAGNOSING AND TREATING FIBRILLATION

摘要

Methods and systems for detecting stability of the arrhythmia or fibrillation, determining whether defibrillation or pacing is needed to disrupt the fibrillation, and, if so, optimizing the timing of low energy therapies to improve efficacy of low energy therapy for defibrillation. By transforming electrogram signals into a discrete series of electrogram conformations, recurrence variables of the electrogram signal can be determined that are highly indicative of sources of the arrhythmia, that predict the likelihood of spontaneous termination of the arrhythmia, and that detect the optimal timing of low energy treatment to terminate the arrhythmia.
