Primary Outcome Measures

Name	Time	Method
Feasibility of DEEP mapping in the atrium during atrial fibrillation ablation procedure - ability to perform effectively with adequate signal quality to interpret results with reference to known DEEP parameters. Signal quality and reproducibility of electrograms will be assessed for consistency and signal-to-noise ratio and consensus from investigators obtained as to whether quality is adequate for interpretation and future application.[At initial AF ablation procedure.];Clinical Recurrence of Atrial Fibrillation as detected on follow-up holter monitor or 12-lead ECG.[End of study follow-up (12 months).]

Secondary Outcome Measures

Name	Time	Method
Relationship of DEEP mapping abnormalities (location and area involved) to abnormal voltage on standard voltage mapping during atrial fibrillation ablation procedure.[At initial AF ablation procedure.];Relationship of DEEP mapping abnormalities (location and area involved) to abnormal activation patterns (for example complex fractionated atrial electrograms or re-entrant activity) on activation mapping during atrial fibrillation ablation procedure.[At initial AF ablation procedure.]
