During VT in two cases with arrhythmogenic right ventricular dysplasia, entrainment criteria, constant fusion beats except for the last entrainment beat, progressive fusion, and a localized conduction block associated with interruption of VT, were demonstrated with rapid ventricular pacing performed during VT. Furthermore, a long conduction interval was present during entrainment from the pacing site to the earliest activation site during VT, indicating the presence of a slow conduction area. VT in these cases was, thus, due to reentry with an area of slow conduction within the circuit.
在两例致心律失常性右心室发育不良患者发生室性心动过速（VT）期间，通过在VT发作时进行快速心室起搏，证实了拖带标准、除最后一个拖带搏动外的恒定融合波、进行性融合以及与VT中断相关的局部传导阻滞。此外，在VT发作期间从起搏部位到最早激动部位的拖带过程中存在较长的传导间期，提示存在缓慢传导区。因此，这些病例中的VT是由于折返环路内存在缓慢传导区所致。
