Because RFCA in a bipoiar fashion can enlarge lesion surface area without increasing the depth, and its particular lesion distributions involved the electrode/tissue interface and the part between the two adjacent electrodes, there is much opportunity to hit the target in bipolar fashion so long as the orientation of the pathway or the any part of reentant circle is not parallel to the electrode-connecting line, whatever at any angle.

因为双极消融法比常规单极消融法有更大的消融面积但不增加深度，而且其组织损伤分布于两电极与组织的交界面和两电极之间区域，所以只要旁道或折返环路的任何部位的走向与两电极的连线不相平行，在任何夹角下双极消融均比单极消融有更多的击中机会。
