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.

- * Results showed no deaths, significant discomfort, or severe device malfunctions post-MRI, with only two instances of minor atrial arrhythmia, both in patients with MR-conditional pacemakers.
- * The findings support that MRI can be safely conducted in patients with CIEDs without adverse effects or changes in device performance, following proper protocols and monitoring.

September 2024
As an alternative to transvenous ICD systems, two non-transvenous ICD systems have been established in recent years: The subcutaneous ICD (S-ICD), which has been established for several years, has a presternal electrode that is implanted subcutaneously and offers a shock function and, to a limited extent, post-shock pacing. In addition, the extravascular ICD (EV-ICD) has been available in Europe since 2023 which does not require transvenous electrodes and offers the option of providing patients with antibradycardic and antitachycardic stimulation in combination with a conventional ICD function. The lead of this device is implanted substernally.

Article Synopsis
- The implantation of electrodes for cardiac devices demands a high level of technical skill and precision, particularly in the right ventricle and atrium, impacting patient safety and therapy effectiveness.
- Focus is placed on the differences between apical and septal stimulation when positioning electrodes in the ventricle.
- The article serves as a practical guide for implanters, detailing the steps for proper electrode placement, but does not cover techniques for physiological stimulation like cardiac resynchronization therapy (CRT) or conduction system pacing (CSP).
Background: Transcatheter aortic valve replacement (TAVR) is an effective and safe therapy for severe aortic stenosis. Rapid or fast pacing is required for implantation, which can be performed via a pre-existing cardiac implantable electric device (CIED). However, safety data on CIEDs for pacing in TAVR are missing.
