摘要:
调节束是右心室的腔内结构，连接右心室间隔和游离壁的前乳头肌，其内走行有右束支及浦肯野纤维，是心律失常的重要起源部位，也称浦肯野介导心律失常。从单纯室性期前收缩到短联律间期室性期前收缩触发的特发性心室颤动，室性心律失常表现为左束支阻滞型，额面电轴朝向左上，胸前导联R/S移行多大于V4导联。射频导管消融可有效治疗室性期前收缩及特发性心室颤动，有效靶点前可发现浦肯野纤维电位，心腔内超声可显示调节束走行，有利于导管贴靠的稳定性及有效消融。
Abstract:
Moderator band(MB) is an important intracavity structure which connects septum and anterior papillary. MB contains right bundle branch and Purkinje fiber,which is an important origin site of arrhythmia,also known as Purkinje-mediated arrhythmia. From simple premature ventricular contraction(PVC) to short-coupled PVC-induced idiopathic ventricular fibrillation,MB originated ventricular arrhythmias manifest as left bundle branch block with left superior axis and R/S transition greater than lead V4,which could be effectively eliminated by radiofrequency ablation.Purkinje potentials could be mapped in the ideal target and intracardiac echocardiography could facilitate ablation by visualization of MB and confirmation the stability of ablation catheter.
