Ventricular arrhythmias originating from the moderator band (MB) often have a distinct morphology
来源于节制索（MB）的室性心律失常有一个独特的形态。

Typically MB arrhythmias have a left bundle branch block pattern, QRS with a late precordial transition (>V4), a rapid down stroke of the QRS in the precordial leads, and a left superior frontal plane axis
典型的MB心律失常有左束支传导阻滞形状，胸前导联QRS波移行延后（V4导联以后），胸前导联QRS波快速下降，和左上额面电轴。

MB arrhythmias are often associated with PVC-induced ventricular fibrillation
MB心律失常与PVC诱导的室颤有关。

Catheter ablation is quite effective at termination of the arrhythmias and facilitated with intracardiac echocardiography (ICE)
导管消融术是终止心律失常的有效方法，可在心腔内超声心动图（ICE）协助下进行。
