What is the recommended positioning for a His bundle pacing lead?

The recommended positioning for a His bundle pacing lead involves placing the lead near the His bundle area under fluoroscopic guidance. This placement is critical because the His bundle is responsible for conducting electrical impulses from the atria to the ventricles, and effective pacing requires the lead to be positioned precisely within this area to ensure proper capture and pacing of the cardiac tissue.

Using fluoroscopic guidance allows the clinician to visualize the anatomy of the heart and the location of the lead in real-time, helping to position the lead accurately. Proper placement is essential to maintain a synchronized contraction of the ventricles, which is the desired outcome of His bundle pacing. Achieving the correct lead position enhances the patient's response to pacing and minimizes complications associated with misplacement.
