Results

Six patients showed fused atrial activation. Post-landiolol administration, the effective refractory period in AP stayed unchanged, while that of the AV node was prolonged. Wenckebach pacing rate via retrograde AV node decreased with landiolol, reducing the minimum ventricular pacing rate for atrial activation dissociation.

Baseline Characteristics

We enrolled 149 patients with PSVT during the study period. Of these, 123 were excluded from this study because 114 patients were diagnosed with atrioventricular nodal reentrant tachycardia, seven with atrial tachycardia, and two with decremental bypass tract. Twenty-six patients were diagnosed with orthodromic AV reciprocating tachycardia (ORT) using a retrograde accessory pathway. Of them, three patients with intermittent preexcitation syndrome and two patients with multiple accessory pathways were excluded.

Participant flow

Twenty-six patients were diagnosed with orthodromic AV reciprocating tachycardia (ORT) using a retrograde accessory pathway. Of them, three patients with intermittent preexcitation syndrome and two patients with multiple accessory pathways were excluded.

Adverse events

No adverse events, including landiolol-related adverse events, were observed.

Outcome measures

The minimal ventricular pacing rate dissociating a fusion of atrial activation was high at baseline; however, landiolol decreased the minimum ventricular pacing rate. Before and after landiolol administration, the ERP and conduction time of AP were unchanged. The conduction time via AP was unchanged, although the pacing rate increased before and after landiolol administration. The ERP of the AV node was prolonged after landiolol administration. The conduction time of the AV node was prolonged but insignificant after landiolol administration. The Wenckebach pacing rate of retrograde AV node conduction decreased after landiolol administration. All the patients underwent radiofrequency catheter ablation during RV pacing under continuous intravenous infusion of landiolol. The current was initiated at 20W and increased to 30W. Acute success was achieved in all the patients. No adverse events, including landiolol-related adverse events, were observed. During the mean follow-up period of 51 weeks, no patient experienced tachycardia recurrence.
