Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Initial Success Rate of Pulmonary Vein Isolation Line Initial success of pulmonary vein isolation line is defined as when either of the following two conditions is met 1: Successful first pass isolation and no premature re-conduction of the pulmonary vein at least 30 minutes after pulmonary vein isolation. 2: When the failure of first pass isolation and early re-conduction is due solely to early excitation in the pulmonary vein by epicardial conduction and the pulmonary vein isolation line is evaluated to be complete. The left and right pulmonary veins will be evaluated separately for each subject in the study. | — |
Secondary
| Measure | Time frame |
