Why the study?
Do contact force parameters predict effective lesion formation better than electrogram characteristics during pulmonary vein isolation in paroxysmal AF patients?
Population
12 paroxysmal atrial fibrillation (AF) patients undergoing pulmonary vein isolation

May support contact force thresholds for lesion assessment in PVI; hypothesis-generating and requires prospective validation before practice change.
Do contact force parameters predict effective lesion formation better than electrogram characteristics during pulmonary vein isolation in paroxysmal AF patients?
Contact force parameters, but not electrogram characteristics or impedance changes, reliably predict effective lesion formation during radiofrequency ablation for atrial fibrillation.
