Over 12% of ventricular arrhythmias from the left ventricle have a source over the epicardial surface of the left ventricle [8]. The most common electrocardiographic template for LVS arrhythmias is V2 lead pattern break qrs [62]. The ablation of ventricular arrhythmias from the LVS is challenging and requires various approaches. Another pattern of outflow tract ventricular arrhythmia is with abrupt R-wave transition in the V3 lead with its source in the septal margin of the LVS [17].
