Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Targeting of most fractionated electrograms first
During catheter ablation of AF patients will have fractionated electrograms targeted. In the experimental group the fractionated electrograms believed to be most critical will be targeted first.
catheter ablation using radiofrequency energy
Active Comparator: Targeting least fractionated electrograms first
During catheter ablation of AF fractionated electrograms are targeted. In this arm the least fractionated electrograms will be targeted first.
