Why the study?
Does low energy DC shock ablation prevent recurrence in patients with refractory atrial flutter?
Does low energy DC shock ablation prevent recurrence in patients with refractory atrial flutter?
Ablation of the atrial flutter substrate with low energy DC shocks is feasible and does not require precise electrophysiological mapping.
No takes yet. Share an insight, caveat, or question.
Low-energy DC ablation may be feasible for refractory flutter without mapping; leaves open recurrence prevention in larger prospective studies.
O’Nunain et al. (1992) studied this question.
