Strengths and Limitations:
This was a prospective interventional study. This study determined the predictive accuracy of adenosine administered 10 minutes after ablation to identify recurrence of pathway conduction at 30 minutes. The electrophysiological characteristics of the accessory pathway in the study population are like that of published data.
Adenosine was not administered prior to ablation to look for any adenosine-sensitive AP conduction. Early recurrence was diagnosed based on conduction at 30 minutes and an ECG taken 24 hours after the procedure. 24-hour continuous ECG monitoring was not done.
