<strong><u>Ventricular Arrhythmias Originating from the Moderator Band</u></strong></p>
<p>
<strong><u></u></strong>- Ventricular arrhythmias originating from the moderator band (MB) often have a distinct morphology</p>
<p>
- 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</p>
<p>
- MB arrhythmias are often associated with PVC-induced ventricular fibrillation</p>
<p>
- Catheter ablation is quite effective at termination of the arrhythmias and facilitated with intracardiac echocardiography (ICE)</p>
