Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Feasibility of 3D-multimodal reconstruction representing an atrial map with respect to following parameters: voltage, excitation/conduction, CFAEs, spiral activation patterns in each patient. 2. Junction of the different maps. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Coincidence of the different phenomena and outcome of the procedure. 2. Quantitative AF burden (in % of FU time, 12 weeks of blanking period post ablation). 3. Safety | — |
