Deep sedation in patients undergoing atrioventricular nodal reentry tachycardia ablation.

Electrophysiological parameters were checked for the two groups and compared before and after the ablation. Results: Electrophysiological parameters were not significantly different in the two groups. In the anesthetic group, patients were more satisfied with the procedure (P value < 0. 001). Conclusions: Intravenous anesthesia could be done safely in patients who underwent electrophysiological procedures. It had no effect on arrhythmia induction or slow pathway ablation in patients with documented AVNRT.
