分析１３例慢－快型房室结折返性心动过速（ＡＶＮＲＴ）患者快径消融产生的问题：发生ＩＩＩ度房室传导阻滞（ＡＶＢ）２例（１５．４％）；术后出现促心律失常的不良后果２例（１５．４％），其中１例因仅阻断快径前传，逆传仍保留而使ＡＶＮＲＴ较术前更易发作，另１例快径前传、逆传部被阻断，因合并隐匿性旁道而使房室折返性心动过速更易发生。４例成功而留有Ｉ度ＡＶＢ者，因心电图不正常而给患者带来一定的心理负担。
Analysis of 13 cases of slow-fast AV nodal reentrant tachycardia (AVNRT) in patients with fast-path ablation problems: the occurrence of III degree atrioventricular block (AVB) in 2 cases (15.4%); 2 cases (15.4%) of the adverse consequences of arrhythmia, of which 1 case of AVNRT was more likely to be attacked than preoperative because of blockade of fast pre-anterior transmission and reverse transmission. Off, due to the co-occult bypass and atrioventricular reentrant tachycardia more likely to occur. 4 cases of success and leaving I AVB who, due to abnormal ECG and give patients a certain psychological burden.
