Left bundle branch pacing is a novel technique where LBB is directly captured by placing the lead deep inside the proximal septum. Electrocardiology plays a major role in identifying the target site on the right side of the septum, monitoring the lead deployment and confirming the LBB-capture. The lead is deployed 1–1.5 cm below the His bundle along an imaginary line connecting distal His signals to right ventricular apex. Rapid deployment of the lead will generate premature ventricular complexes which will guide in reaching the left bundle branch area. Several ECG based criteria will assist in confirming the conduction system capture. Further randomized trials will help in establishing the long-term safety of this novel pacing modality.

左束支起搏是一种新技术，通过将导线放置在近端隔膜深处，直接捕获 LBB。心电图在确定隔膜右侧的目标部位、监测导线部署和确认 LBB 捕获方面发挥着重要作用。沿将远端 His 信号连接到右心室心尖的假想线将导线部署在希氏束下方 1-1.5 厘米处。导线的快速部署将产生室性早搏，这将引导到达左束支区域。几个基于 ECG 的标准将有助于确认传导系统捕获。进一步的随机试验将有助于确定这种新型起搏方式的长期安全性。
