2. Figure 1
Types of procedures performed. AFL = atrial flutter; AP = accessory pathway; AT = atrial tachycardia; AVNRT = atrioventricular nodal reentrant tachycardia; NAV Abl = atrioventricular nodal ablation; VT = ventricular tachycardia.

3. Figure 2
Acute success rate. Since all patients in group 1 had AVNRT, AFL, or AP, a between-group comparison of outcomes for specific arrhythmia types was possible only for these categories. AFL = atrial flutter; AP = accessory pathway; AVNRT = atrioventricular nodal reentrant tachycardia.

5. Figure 4
Learning curve obtained in patients with atrioventricular nodal reentrant tachycardia (AVNRT) in group 2. Procedure time shows a nonsignificant trend toward progressive shortening with increasing experience.
