Comparison of electrogram characteristics in persistent atrial fibrillation

ConclusionMultiple techniques can be employed for electrogram analysis in AF. In this analysis of eight  different electrogram characteristics, seven were poorly to moderately correlated and do not identify similar locations. Only some characteristics were predictive of ablation outcome. Further studies to consider electrogram properties, perhaps in combination, for categorizing and/or mapping AF are warranted.
