RESULTS
We performed ablation for atrial flutter without ablation for other arrhythmias on 132 patients between October 2013 and September 2018. All received an adenosine test at 5 minutes. The test resulted in transient recurrence of clockwise conduction across the CTI in 3 patients (2.3%), all of whom went on to have a persistent recurrence of bidirectional conduction across the CTI at 6-10 minutes respectively. An additional 3 patients had persistent recurrence of CTI conduction at 17-19 minutes despite having had a negative adenosine test.
