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.
