Key result
Radiofrequency catheter ablation of atrial arrhythmias achieved an overall acute success rate of 90.5% (38 of 42 arrhythmias) and caused no complications from energy application.

Does radiofrequency catheter ablation improve acute success and long-term rhythm control in patients with drug-refractory atrial arrhythmias?
Radiofrequency catheter ablation is highly effective and safe for treating various drug-refractory atrial arrhythmias, though repeat procedures may be needed for long-term success.
Lesh et al. (1994) conducted an observational in Atrial arrhythmias (n=37). Radiofrequency catheter ablation was evaluated on Inability to reinduce tachycardia (acute success). Radiofrequency catheter ablation of atrial arrhythmias achieved an overall acute success rate of 90.5% (38 of 42 arrhythmias) and caused no complications from energy application.
