DISCUSSION
In this study, an adenosine test of 10mg at 5 minutes after RF ablation
gave 50% sensitivity for identifying the 4.6% of cases in which CTI
conduction would recur later in the 20-minute waiting period. A negative
adenosine test gave 97.7% probability that conduction would not recur
within this period. In no case was a positive adenosine test followed by
continuance of CTI block to 20 minutes after ablation.
