Table 2 Mapping and ablation of VAs in the transaortic group, transseptal group and trans-DGCV group

From: Approach selection of radiofrequency catheter ablation for ventricular arrhythmias originating from the left ventricular summit: potential relevance of Pseudo Delta wave, Intrinsicoid deflection time, maximal deflection index

Group Time of earliest ventricular activation preceding QRS onset, ms Number of similar lead counts between spontaneous PVCs and Pace RF lesions prior to success Target site discharge time for PVCs/VT disappearance, s Ablation time, s Procedure time, min X-ray exposure time, min
