[Left bundle branch (area) pacing: lead positioning and implant criteria-step for step].

Left bundle branch area pacing is currently the most common form of physiological pacing prior to His bundle pacing. It is intended to prevent or correct the development of pacemaker-induced cardiomyopathy and is being used more and more frequently. In order to be able to perform this successfully, knowledge regarding the specific anatomy and radiological anatomy as well as the ECG criteria for left bundle branch pacing is required in addition to knowledge of the tools. In this article, the technical requirements and steps for successful implantation are summarized and pitfalls are highlighted.
