摘要

背景目前，间断记录技术常用于进行左束支（LBB）起搏（LBBP）。然而，这种方法需要反复测试，以确认是否捕捉到左束支并避免穿孔。病例摘要在一名 86 岁的妇女身上使用不间断记录技术进行了左束支起搏。结论连续映射和记录技术有助于更准确地定位室间隔 LBBP 导联。

Left bundle branch pacing guide by uninterrupted recording of intrinsic filtered and unfiltered intracardiac electrograms

Background

Currently, the interrupted recording technique is commonly used to perform left bundle branch (LBB) pacing (LBBP). However, this method requires repeated testing to confirm that the LBB is captured and perforations are avoided. An automated solution may make this repetitive work easier.

Case summary

LBBP was performed using an uninterrupted recording technique in an 86-year-old woman. Lead position and LBB capture was confirmed by the characteristics of the intrinsic filtered and unfiltered intracardiac electrograms.

Conclusion

Continuous mapping and recording technique may help achieve more accurate positioning of LBBP lead in the ventricular septum.
