Results: 2 patients with B-WPW showed disappearance of preexcitation 1-month post ablation, Persistent complete atrioventricular block and Wenckebach AV block occurred in 2 patients with AVNRT respectively within 1-week after ablation.

结果：2例B-WPW术后1个月复查心电图预激消失，2例AVNRT分别于术后3d和1周出现持续度房室传导阻滞和度型房室传导阻滞，经激素治疗后房室传导均恢复正常。
