Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The overall goal of this project is to test the feasibility of performing real-time electrogram morphology recurrence (EMR) mapping in patients with persistent atrial fibrillation (AF) to locate areas of high electrogram morphology recurrence rate. The Investigator believe that the EMR mapping can be integrated into cardiac mapping and used to identify potential sites for ablation. Furthermore, this study could help demonstrate the efficacy of this technology's ability to terminate or slow AF. The Investigator will test this technology on ten subjects undergoing a second ablation procedure. The Investigator will map the AF utilizing the EMR to indicate locations of stable activity and ablate the area. The Investigator believes that the study could produce acute AF termination or AF cycle length slowing. In addition to testing the real-time electrogram morphology recurrence mapping, the study would also like to determine the acute effects of radiofrequency ablation of areas of high recurrence rates and determine long term freedom from AF following ablation of areas of high recurrence rates.
