摘要:
目的 旨在评价房室旁路射频消融后心脏的复极改变情况及其特征。 方法 回顾性分析132例房室旁路射频消融术后体表心电图T波改变情况。结果 [ HTSS]80例隐匿性旁路在射频消融术后无1例出现心脏复极改变,52例显性旁路中有20例(占39 %)术后出现明显T波变化,其中完全性旁路(QRS≥0.14 s)占19例,而不完全性旁路(QRS＜0.14 s)仅占1例。室间隔部的旁路更易出现术后复极异常。结论 显性房室旁路消融 术后可以出现酷似心肌缺血的T波改变。
Abstract:
AIM To estimate the change and feature of cardiac repolarization wi th atrioventricular accessory pathway by radiofrequency catheter ablation (RFCA) . METHODS 132 patients with A-V accessory pathway underwent RFCA,and observed T wave change using 12-lead electrocardiogram. RESULTS Amo ng the 80 patients with conceal accessory pathway,no one had episodes of T wave change by RFCA. However 20(39%) patients appeared obvious T wave change among th e 52 patients with non-conceal assessory pathway after RFCA,including the 19 pa tients they passed through cmplete accessory pathway (QRS duration≥140 ms) and only one patient is incomplete accessory pathway (QRS duration ＜140 ms). The T w ave change was more common in the patients with the ventricular septal accessory pathway after RFCA. CONCLUSION After RFCA,Wolff-Parkinson-White syn drome may occur T wave change that mimic ischemia.
