COMParison of Algorithms for Rotational Evaluation in Atrial Fibrillation
COMParison of Algorithms for Rotational Evaluation in Atrial Fibrillation
This is a cohort study to evaluate algorithms for mapping atrial fibrillation and for
 detecting rotational activity.
In this study, the investigators will analyze electrograms collected routinely at clinical
 electrophysiology study (EPS) in patients undergoing ablation for atrial fibrillation. These
 electrograms will be recorded from a variety of clinically approved catheters under standard
 of care conditions, and will be analyzed to better understand the mechanisms for atrial
 fibrillation and its relationship to outcomes.

 The investigators anticipate analyzing data from 200 patients through December 2017.
Inclusion Criteria:

 -  aged 21-80 yrs who underwent electrophysiology study for ablation of Atrial
 Fibrillation

 Exclusion Criteria:

 -  Poor data quality of recordings of AF
