Key result
Simultaneous noncontact mapping of the left atrium identified ectopic foci from a single beat, guiding successful radiofrequency catheter ablation in 75% (9 of 12) of attempted patients.
Why the study?
Does simultaneous noncontact mapping allow identification of ectopic foci and guide radiofrequency catheter ablation in patients with paroxysmal atrial fibrillation?
Observational (n=17)
Does simultaneous noncontact mapping allow identification of ectopic foci and guide radiofrequency catheter ablation in patients with paroxysmal atrial fibrillation?
Simultaneous noncontact mapping effectively identifies arrhythmogenic pulmonary and extrapulmonary vein foci from a single beat, facilitating targeted radiofrequency catheter ablation in patients with paroxysmal atrial fibrillation.

May support single-beat noncontact mapping for focal AF ablation; hypothesis-generating and requires randomized trials before practice change.
Hindricks et al. (2001) conducted an observational in paroxysmal atrial fibrillation (n=17). Simultaneous noncontact mapping was evaluated on Successful ablation of atrial fibrillation. Simultaneous noncontact mapping of the left atrium identified ectopic foci from a single beat, guiding successful radiofrequency catheter ablation in 75% (9 of 12) of attempted patients.
