摘要(Abstract)：

左后分支型室性心动过速（LPFVT）是分支型室性心动过速中最常见的亚型，多发于无结构性心脏病的年轻患者。其发病机制主要与左心室后间隔浦肯野纤维网络的折返活动相关，随着电生理检查和射频消融技术的不断发展，针对LPFVT的治疗策略不断优化，包括基于P1电位的靶向消融、左心室中下间隔区域的线性消融，以及靶向碎裂前传浦肯野电位（FAP）的新兴标测方法。此外，近期研究进一步揭示了假腱索及心室肌在LPFVT折返环路中的可能作用，强化了LPFVT病理生理机制的复杂性。电解剖标测技术的应用显著提升了术中精准定位的能力，为难以诱发或表现为非持续性室性心动过速的LPFVT患者提供了更加安全、有效的治疗手段。本文对LPFVT的病理机制及其消融策略进行了系统性回顾，为其临床诊疗提供理论支持和实践指导。
