Key result
Internal cardioversion restored sinus rhythm in 83% (20 of 24) of patients with chronic atrial fibrillation who had previously failed external cardioversion.
Why the study?
Does internal cardioversion restore sinus rhythm in patients with chronic atrial fibrillation who failed external cardioversion?
Does internal cardioversion restore sinus rhythm in patients with chronic atrial fibrillation who failed external cardioversion?
Internal cardioversion using high-energy shocks can successfully restore sinus rhythm in a subset of patients with chronic atrial fibrillation refractory to external cardioversion.

May offer rescue option after external failure; leaves open safety and efficacy in randomized trials.
Samuel Lévy (1990) studied Chronic atrial fibrillation (n=24). Internal cardioversion was evaluated on Restoration of sinus rhythm. Internal cardioversion restored sinus rhythm in 83% (20 of 24) of patients with chronic atrial fibrillation who had previously failed external cardioversion.
